Today lets tackle a very familiar problem. You have a bunch of very long, complicated file names & paths. Your boss wants a list of files extracted from these paths, like below:

Of course nothing is impossible. You just need correct ingredients.

I cannot help you with a strong cup of coffee, so go and get it. I will wait…
Back already? well, lets start the formula magic then.
Extracting file name from a path
If you observe the file paths carefully, to extract the file name, we need to know,
- Position of last \ in the full path text
Of course there are many methods find where the last \ is. You can find a very excellent summary of these techniques in our formula forensics #21 – finding the 4th slash.
Today, let us see a new technique (well, sort of).
Finding the position of last \ using formulas
Before writing any formula, first let me clarify the only assumption:
- File path is in cell B4
Now, last \ is nothing but first \ when read from right.
Read that line again.
Got it? Good, lets move on.
How do we find the first \ from right?
If we can list down all individual characters from path right to left, then we just have to find the first \ in that.
Listing down individual characters from a given text
To get 5th character from text in B4, we can use MID formula like this:
=MID(B4,5,1)
Suppose you want both 5th and 6th characters from B4, you can use:
=MID(B4,{5,6},1)
This formula returns an array of 5th and 6th characters from the text in B4.
Cool, extending the logic, =MID(B4, {6,5},1) would give 6th & 5th characters in B4.
Idea!
If we can replace {6,5} with decreasing numbers starting from length of text B4 all the way to 1, then we can list all characters in B4, right to left.
But this leads us to next problem – listing numbers from a specific value (length of B4) to 1 in descending order.
Listing numbers from n to 1 in that order
We can use ROW() formula to generate sequence of numbers like this:
=ROW(1:10) will give {1,2,3…,10}
note: this returns an array, so you need to use it with Ctrl+Shift+Enter
So if we can use =ROW(1:LEN(B4)) we could get numbers from 1 to length of text in B4 {1,2….LEN(B4)}
Unfortunately this will not work as 1:LEN(B4) is not a valid reference.
But we can fix that with INDIRECT, like this:
=ROW(INDIRECT(“1:” & LEN(B4)))
Tip: INDIRECT formula lets you construct a reference by using values in other cells as shown above.
Alternative: You can also use OFFSET to get the same result like this: =ROW(OFFSET($A$1,,,LEN(B4))). More on OFFSET here.
But wait…
So far, we have only generated numbers from 1 to n. But we need numbers from n to 1.
No sweat, we just subtract the numbers {1,2…n} from n+1 to get the list {n,n-1,n-2….2,1}
Like this:
=LEN(B4)+1 – ROW(INDIRECT(“1:” & LEN(B4)))
Using these numbers to list characters in file path in reverse order
Take a sip of that coffee, its getting cold!
Now, lets integrate our numbers in to MID like this:
=MID(B4, LEN(B4)+1 – ROW(INDIRECT(“1:” & LEN(B4))), 1)
The blue portion gives you numbers {n…2,1}
The orange portion gives you letters from right to left.
But we wanted the last \
Oh right. We do not need these letters from right to left. We instead want to find the last \ in our file path. So now we just ask Excel where the first \ is in this reversed text.
=MATCH(“\”, MID(B4, LEN(B4)+1 – ROW(INDIRECT(“1:” & LEN(B4))), 1), 0)
Blue portion gives you letters in reverse order
Orange portion finds the first \ in that.
Tip: Learn more about MATCH formula.
Extract the file name
Once you know where the last \ is, finding the file name is easy.
use =MID(B4, position_of_last_slash + 1, LEN(B4))
We need to +1 because we do not want the slash in our file name.
Demo of the entire formula in action
Okay, lets see all these steps in action in one go.

How to find the extension?
Extension is few letters added at the end of file to indicate its type. For example, excel files usually have xls, xlsx, xlsm as extension.
So how to find this extension?
Extension & file name are separated by a dot .
But often file name itself can have a dot.
In other words, Extension is text in the file name followed by last dot.
Sounds like same problem as finding the last \ and extracting file name. So I will skip the details.
But assuming the file name is in D4, extension can be found with =RIGHT(D4,MATCH(“.”,MID(D4,LEN(D4)-ROW(INDIRECT(“1:”&LEN(D4))),1),0))
NOTE on both formulas
Both file name & extension formulas are array formulas. This means after typing them, you need to press Ctrl+Shift+Enter to see correct result.
Bonus tip: Getting the file names & path from a folder
If you ever want to list down all files in a folder use this.
- Open command prompt (Start > Run > Cmd or Start > Cmd)
- Go to the folder using CD
- Type DIR /s/b >files.csv
- Close command prompt
Now you can see all the files in that folder in files.csv. Double click on it to open in Excel and run your magic 🙂

How do you extract file names & as such?
Do you use formulas or do you rely on some other technique to extract portions of text like file names, mail addresses etc. Please share your tips & ideas using comments.
Extract often? You will dig this.

WOW, is all I can say.
I could not have imagined a dynamic dashboard without getting approved software budget and a team of people involved to create it. Given that I am a relative newbie to excel and actually got here by looking for pivit table help, I imagine that i would not be able to make anything myself. But armed with the demo excel sheet I will press buttons (and I will report back how that went;-)
Claudia
Good stuff Chandoo, thanks
The slicer buttons take up quite a bit of room on the dashboard
Is there a way to make the buttons smaller so we can have more room for charts, tables, and commentary?
Kind regards,
Winston
You can resize the slicers! When you click the slicers you can change the height and width of columns and slicers. You can also, under slicer style click "New slicer style" where you can define your own style, which enables you to change most things, including font size.
I hadn't seen the Group Option used as you did for the Duration PivotTable. And thanks for showing how to remove the Field Buttons on a PivotChart, I loathe them with all my heart.
Fantastic design and a great dashboard.
@Claudia.. I am glad you like it. Do let us know how your adventures go.
@Winston: You can resize slicers or increase the number of columns inside. Unfortunately, we can not readjust the font sizes in slicers. So when you resize, you will see partial text.
@Gregory: Thank you. I am happy you like it 🙂
Hi Chandoo, your dashboards are really professional and simple. I do have some question, if I have the following scenario, could you help to advise : -different data sources eg monthly
-calculations percentile
-%difference between financial year
Thank you so much!
Hi,
Thanks for your great information.It has helped me a lot.
Now,I can build my excel addin for Excel 2010 better with your tips.
Hi chandoo i am new reader for ur site.and really found good stuff and temp. But i suggest u 2 put a guidance step sheet in temp so anyone can understand easily.and also help me to become awesome as ur noume.

Chandoo, Wow these are very powerful reports. I will be implementing them straight away. It will save me hours of work. Thankyou so much.
Hi Chandoo,
I love the Slicer, but how do I link a slicer for different data sheets e.g.: Client data on one tab and products on another tab, as I find that as long as you use pivot tables off the same data you can link the Pivot tables using Slicer connections.
Regards
Paul
I appreciate the work you have posted on your website - very informative and easy to understand. I just wanted to inform you that you can make selections within the slicer too by using Ctrl and selecting the fields you want to group and use as filter.
I had a question regarding the data used in pivot tables. Is there a way to update the data (eg. a new customer entry) and have the pivot tables and the linked charts in dashboard automatically update? I will search for the answer in other posts so ignore if you have covered it elsewhere.
Thanks again and keep up the good work.

Dear All,
Me too is a die hard fan of Slicer. it's requirement was arise when management is feeling it difficult to juggle with filters for sales of a particular location, Product Category in Pivot Table.
Got very positive response when introduced to tackle the above situation. furthermore in slicer setting there would be option to enable or disable deleted data is handy for particular scenario.
These are eye catching color themes would be like icing on the cake.
There is one more feature of excel 2010 which proves to be tool for great time saving is "Repeat Labels" in Pivot Tables.
This is fantastic!! Your steps were super to easy follow. I can't wait to show my new dashboard off to the boss. Thank you so much!
This might be a little unrelated but I'd like to know which software was used to record your on screen actions? I'd like to use it for tutorials on models that I build for my customers. Thanks!
@Van

The slicers are coming in a sorted order... How can i get it in the way it appears in my original data.... The settings show to sort them A to Z or the other way round but they are option boxes and can not be unchecked... What are my options????
[...] Using slicers to make a dynamic dashboard in Excel [...]
I watched the video and then worked through an example of my own, also telephone costs by coincidence. It took me about 30 minutes to do everything. Once you've understood the basics of pivot tables and slicers, all that limits you is your imagination!
The only thing missing from the video is now to change the number of columns in a slicer: Right click a slicer then Size and Properties, Position and Layout, Layout, Number of Columns ...
Good page and video.

How do you insert 'Year' in the Pivot Table Field List if it doesnt exist in the Master table???
Thanks
Hi,
Can I disable the multi-selection of the slicer to only allow one selection at a time?
Thanks in Advance
@Manu.. as of Excel 2013, this is not supported yet. But you can remove slicer heading, clear filter button and style it so that it looks like a single selection. You can also use Macros to ignore previous selection upon multiple selection, but I would not recommend it.
For an example on styling see - Interactive Pivot Calendar
Awesome guide! The dashboard I made blew people away. I do have one question. I want the chart title to match what I have selected. How can I do this without writing macros?
@Devin
Lets say what you have selected in in A1
Select the Chart then Select the Title
Click in the Formula Bar and type =A1
enter or click the small arrow to the left of the Formula Bar
Enjoy
Love the slicers and use them often in my dashboards. Question about the data (specifically the date) I see the "date of call" column but was wondering how were you able to filter on slicers by year and month when there is only a date of call entered into the data?
Thanks for your help!
Thanks for taking the time to create this interesting and very useful tutorial!
I was able to create a similar dashboard in a short time after watching your tutorial. The problem I am having now is how to update the pivot tables and dashboard graphs when a change is made in the raw data. I tried two methods; Change data Source and Refresh. When I used Change Data Source (Options-> Change data source) the values in the pivot tables didn't update. When I tried refresh the values in the pivot tables disappeared as well as the information in the graphs, since the data in the pivot tables no longer existed.
I have been searching for a solution for a while now but I have unfortunately not been able to solve this problem yet. Any help someone can provide is GREATLY appreciated.
All the best
Hi, looks great, but how valuable is power view when it comes to financial data? I've been having trouble trying to visualize how I would use power view to report of financial data.
Hi Chandoo, you are awesome! Thanks for the good work!
there is duplication for my slicer, probably cause i choose date, time as my options. i changed it to date but still theres a duplication of the same date
Just Great! Thank you for the time to put this together and teach us.
Alex Cardoso from Indaiatuba, Brazil.
First of all I would like to thank you guys for this post I used this amazing tool with the help of your tutorial to create a dashboard for one single account and my regional manager said "good job, it looks very profesional" she was so impresed that now she wants one daschboard with all the acounts and services she is going to replace her KPI reports with my report !! I smell a promotion!! My demand was a new laptop with MS 2010 and it was granted. now I have allot of work and many many questions to post .. kudos
Hi Chandoo
I want to say thanks first because i loved ur tutorials
i have a small doubt how to insert slicer from external connections
i searched every where could you please explain how to insert a slicer from external source
@Krishna Prasad
use external source data as pivot table then you will be able to use slicer.
Hello Chandoo,
How to get rid of the > items in Months slicer?
They are appearing when there is a grouping on the date field in pivot
Thanks
Hi Chandoo,
One problem always bothers me when i use slicer. I have no idea aobut how to change the number format in slicer. Want to display number in slicer as general format, but it always displays other number format such as date.
I check my source data and it doesn't effect the number format.
Look forward you or any EXPERTS to solve it. Thanks very much!
In the end, This website is awesome!!!
Hi Emma,
Were you able to resolve your query? I have a similar problem. I use Excel 2013 and the field I'm dropping into the slicer is a currency field ($1.00, $1.05, $1.10 etc.) representing the exchange rates that the user can choose from. The items in the slicer revert back to general format (1, 1.05, 1.1, etc.) although the source field is formatted as currency field. Is there a way to fix this?
@Sunil & Emma: You can create a new column in your raw data which has currency as text, using the TEXT formula like this =TEXT(currency_val, "$#,##.00"). Use this column to create the slicer.
Thanks for the response Chandoo. It works as you suggested. However, if the users were to pick more than one item in the window I'd like to know what is the max value and utilise that value in a DAX formula.
Also... there is no issue if I were to throw a slicer over a normal pivot. The trouble comes when I choose the 'Add this data to the Data Model' option which I need for the PowerPivot.
Hi Chandoo (Or others)
Is there a way to make the color change, when the value changing after the use of a slicer?
Lets say the value is 4,5, when i press the slicer, and the value change to 3,5 i would like the color to change. Can anyone help?
Thank you.
Hi Chandoo,
It was very useful video for me. Thanks.
But I have one question to ask.
How can I connect data which is growing in size (rows, records) by time (daily, monthly etc.) to this kind of dashboard?
Or it is only on select number of data?
Thank you.
Chandoo zindabad!
Hi Chandoo,
I have been able to create something similar quite easily. The problem that I am facing is that I want to keep the Top 10 filters permanently. If I select one option and then clear the filter, the chart removes the Top 10 filter; I want it to go back to Top 10 filter.
Is there a solution to this problem?
Regards
Thanks a lot for the tutorial and for the demo file!
I have the same problem of Angela: after clearing the filter applyed on P1, the filter on P1 shows all the customers without filtering top 10 (as it was before).
Thanks!
Federico
Go to your pivot table, right-click and choose "pivot table options." On the "Totals & Filters" tab check "Allow multiple filters per field."
Justin, thank you so much!
now after clearing the filter applyed on P1, the filter on P1 shows again top 10 customers.

Very useful. Learned a new skill today. Thanks a ton!
Hi Chandoo,
This is fantastic! It's going to really help me with some operational reports I develop regularly. Two questions I'm hoping you can answer for me:
1. How can I use one slicer to manipulate two different pivot charts that came from two different pivot tables?
2. If I have a slicer in an excel and share that with someone who is on older versions of Excel - what will it look like to them?
thanks!
Hello Chandoo!
I love the dashboards and have been able to make quite a few, my puzzle is when I am connecting the pivot charts to the slicers, I have to do each individual one and check every single slicer (usually I have about 12, so I end up having to check the 12 check boxes 12 times to connect everything) am I missing something? Is there an easier way to do this?
Thanks!

Hi,
I've built a dashboard on Excel 2010 using Pivot tables and slicers.
What I would like to do now is duplicate the dashboard on another tab, having it extract from another data source (format is identical to the 1st data source).
I'm extracting the same metrics, but each data sources measure different product lines.
Could anyone help me out?
Thanks in advance,

Thank you so much. I learned so much about the slicer because of the video. Just got a quick question. Say I got 100+ Customer name bottons in one of the slicer, and it is time consuming to scroll up and down to find the one to select. Is there anyway I can set in the slicer setting that when I type "E", it automatically take the selectionto to where all the "E" starts? Thanks
