After a really long wait finally I have used … Excel 2007 (drum roll) and contrary to what many people think, I have found Excel 2007 to be a very well designed piece of software. Of course there are various issues with it and I am sure folks at MS are working on them so that next versions of MS Office are much more pleasant and simpler to use.
I wanted to share 10 wow factors in Excel 2007 that may convince you to try it.
1. The interface is gorgeous and easy on eyes
The Excel 2007 interface is very well polished and looks neat. It is easy on eyes with simple colors. All the file related activities can be accessed from office button on the top-left corner, while ribbon UI provides access to all excel features.
2. When you right click on a cell it shows formatting options as well
Usually when you right click on a cell (or a range of cells) it is to format them. Now you can do that even faster. When you right click excel 2007 shows the standard formatting options as well.
3. Status bar now shows average and count as well
Remember how you can select a bunch of cells in excel 2003 and earlier and findout out their sum (or average or count) quickly by looking at status bar ? Well, now you can find out average, count and sum from status bar (actually you can add more options, just right click on status bar and choose the statistics you want)
4. Improved conditional formatting with micro charts
One of the significant new features of Excel 2007 is improved conditional formatting. It has all the goodness of excel 2003’s conditional formatting and on top added new features like incell micro charts. They are very easy to use.
5. You can format tables in a jiffy
One of the most common formatting tasks is table formatting. Excel 2007 totally automated it with some gorgeous table formats. You can customized these styles very easily.
6. They have a Remove Duplicates button !!!
That is right, finally a remove duplicates button. Select the data, press this button and mention whether you want to overwrite or paste in another place and that is all. Now, if only they could add other common data clean up tasks as buttons…
7. The default chart formatting is way better than that of Excel 2003
The default charts look much much better than those generated in earlier versions of Excel. What more, they have disabled annoyances like font-scaling by default. 🙂
8. Better and Visually Appealing Color Scheme
The default color scheme is very good and provides excellent contrast when used in charts and tables. What more, the colors are no longer limited to 56 but you can add your own colors with much ease.
9. Ribbon is not that difficult to use
The Ribbon UI has been criticized by lot of people. But it is not really that difficult to use and get used to. Although you would need 2-3 clicks for activities that previously took 1-2 clicks. It would have been excellent if MS had provided an option to switch to classic menu navigation.
10. Despite the new look most of the dialogs are same
Even though Excel 2007 may seem like a huge leap from Excel 2003, the underlying dialog boxes, customization options are all same as that of Excel 2003. For eg. you can see that Ctrl + 1 on a cell produces the above “format cells” dialog box which is almost same what you get in 2003 version of excel.
Another thing is all the excel 2003 keyboard shortcuts work in excel 2007, so power users who have learned the shortcuts over a period need not worry about productivity loss.
All in all, I found Excel 2007 pretty ok except for few glitches. I am planning to install (not upgrade) it on my personal computer as well so that I can experiment and learn more.
What is your take on Excel 2007 ? What are the features that wowed you?
PS: This review is based on my first look at the Excel 2007 and not an exhaustive review. I haven’t tested features like pivot tables, VBA, new formulas etc. Stay tuned for more excel 2007 articles in the coming weeks.

Hi Chandoo, I need you help in the following problem.
I'm trying to get a direccion from a found result. With this dirreccion I will want the before cell value. For example, If result of a find is 38 localized in cell $C$2, I need to get previus value (cell $B$2 ), maybe Andrés.
Do you know some way to do that?
Thank you for you help.
Hi Chandoo
Thanks for this. One thing though: In my pre-2007 version of Excel, the COUNTIF function doesn't recognise a semicolon (;), but requires a comma.
Is the semicolon an Excel 2007 thing?
Jair... I am not sure I understand what you want. what do you mean by Dirreccion?
@Lincoln: I am sorry, often I forget that I am using European version of excel where the delimiter is ; instead of ,. I have corrected the formula now.
Thanks for this nice tip, i used to do a find all after filling every new items which was cumbersome.
Do you know a way to extend this validation search to other tabs/sheets ?
Thanks for you attention. I'm trying to get of value continue from a found value. Let me show a example:
Name Years
John 35
Maria 28
Teresa 32
If I search the max years, the result is 35, but I need that result to be John. Do you know how I can do it?
@Subbu.. you can easily extend the validation to other sheets by pasting the data validations. See the latest article here: http://chandoo.org/wp/2009/10/28/copy-data-validations/
@Jair.. you can use the large() or small() formulas to do this. for eg. =index(A1:A3,large(B1:B3,1)) will get you the name of the person with highest "years". More help here: http://chandoo.org/excel-formulas/large.html
Hi, I don't know if I'm using bad the formula or its performance is diferent for my Office version. Large() formula return the value in the cell, in my example 35. The index() formula use a range, row and column. I'm using the large() as number of row, and it is bad because into the range don't have row 35. This is my perception. What do you think?
Hi, I going to prove, with this solution by JLD http://jldexcelsp.blogspot.com/2008/07/extraer-direccion-de-celda-en-matriz.html
Hello,
I am trying to attempt data validation in Excel Mobile, but the DV tool isnt available. I want to prevent duplicates is all, any advice on acheiving this in Excel Mobile? Thanks..
@Jair... my french aint that good. it starts at "merci" and ends at "beau coup".
Anyhow, you need to merge the large with vlookup to do this. I am not sure if you have solved the problem. Otherwise let me know with details and I can write the formula in comments.
@Chad... I have never used excel mobile, so I have no idea. May be they have not implemented data validations in excel mobile.
Any excel mobile users out there?
Hi Chandoo, the proposed solution by JlD is interesting. He created a macro to get values when the matrix is not one dimensional, how on my problem. This fuction for me.
I would like to share you my work, how can I upload?
@Jair.. sorry for such a delayed reply.. you can upload the files to skydrive and link them here. Or you can email them to me at chandoo.d @ gmail.com and I will upload them somewhere. But it could take forever if you email files to me as I am a bit lazy.

Hi,
Can you help me in Microstrategy?
Br,
Moin
really wonderful article. I feel it is implementing Primary Key concept into spreadsheets.
Hi article on data validation. Excel is a very versatile platform to work with and we use it for all kinds of data tabulation. In fact this must have been the most rudimentary data management tools I must have worked with and knowing such tips only adds functuionality to our user experience. Great article. looking forawrd to read more.
Hi Chandoo,
Thanks for such a nice idea.
I tried copy paste the data into the validated area, but the pop-up msg (warning msg) doesn't came. Is it something that we need to update the data manually each time,.
Do we have any option where we can bulk upload the number and it throws a warning message that the data already exits and do we want to continue with this ?
Please do reply me.
Thank you.
Regards,
Vasanth.
It was really useful chandoo...thanks a lot...
Tried this in excel 2010 and it did not work?
Could the newer excel have changed that much?
@Leo
It works fine in Excel 2010
The formula used above =COUNTIF($B$4:$B$11,B4)<=1
only applies to the range B4:B11
Did you adjust the range to your data?
This page helped me accurately to find solution of my question. thanx
we want to prevent duplicate entries in three columns combined, using data validation, i.e. say, column A has first name and Column B has middle name, Column C has last name. the first name can be duplicate, middle name can be duplicate, last name can be duplicate, but not all three at the same time.

Hi, I've tried above validation method to prevent duplicate value from entering into the cells. It's work, when user key in the data into the selected range. However, it's not working when user copy-&-paste the info into the same range.
Please advice. Thanks.
Hi Chandoo,
Does it work in Excel 2007?
Please Reply
thanks chandoo........
it does not work when data is copy pasted...any solution for this??
hi i m shaloo and i want to know in excel if i write duplicate no.then it says or show about we are write duplicate no.
Hi Chandoo
I've tried using this with a Named Range, which is actually a column in a Table as DV wont accept a table reference, and it wont work.
Also tried using Offset to specify the Named Range, but that wont work either.
Is it possible to use Named Ranges with DV?
Thanks
Kris
I have tried the above formula on a table column. The Error box does not pop up, there is only the small ! next to the cell with the duplicate. The column I am working with is formulas that produce a date. Is the reason it doesn't work that the cells contain formulas rather than data?
The formula works but only if I enter data in cell above it. So for example, if I have "123" in B11 it does not allow me to enter "123" in B10, B9, B8, etc. But I can still enter "123" in B12. Please help! 🙂
Great tip.. thanks a lot
I have 21 years of experience working as data entry assistant. I constantly read several blogs to keep myself up-to-date with the advances in data entry profession. I really enjoyed this blog post. From my several years of experience, I agree with you 100% when you say, “ We all know that data validation is a very useful feature in Excel. You can use data validation to create a drop-down list in a cell and limit the values user can enter. ”
Keep blogging. I will come here again.
