Often we deal with data where numbers are buried inside text and we need to extract them. Today morning I had such task. As you know, we recently ran a survey asking how much salary you make. We had 1800 responses to it so far. I took the data to Excel to analyze it. And surprise! the numbers are a mess. Here is a sample of the data.
Now, how do I extract the salary amounts from this without typing the values?
My first thought is to write a user defined function to extract the number from text. But I usually shy away from VBA. So I wanted to see if there is a formula based approach to extract the number from text.
Using formulas to extract number from text
To extract number from a text, we need to know 2 things:
- Starting position of the number in text
- Length of the number
For example, in text US $ 31330.00 the number starts at 6th letter and has a length of 8.
So, if we can write formulas to get 1 & 2, then we can combine them in MID formula to extract the number from text!
Finding the starting position of number in text
To find the starting position, we need to find the first character which is a number (0 to 9). In other words, if we can find the positions of 0 to 9 inside the given text, then the minimum of all such positions would be starting position.
Sounds complicated?!? Well, in that case look at the formula and then you will understand why this works.
Assuming the text is in A1 and the range lstNumbers contains 0 to 9, below formula finds starting position
{=MIN(IFERROR(FIND(lstNumbers,A1),””))}
You need to array enter it (CTRL+SHIFT+Enter)
How this formula works?
FIND(lstNumbers, A1) portion: This part finds where each of the numbers 0 to 9 occur in the text in A1. If a match is found, the position is returned. Else we get an error. For US $ 31330.00 the values would be,
{10;7;#VALUE!;6;#VALUE!;#VALUE!;#VALUE!;#VALUE!;#VALUE!;#VALUE!}
Meaning, 0 occurs at 10th position, 1 occurs at 7th position, 3 occurs at 6th position and everything else (2,4,5,6,7,8,9) do not occur in the number.
IFERROR(…,””) portion: Then, we replace errors with empty spaces so that MIN could work its magic.
At this stage, the result would be, {10;7;””;6;””;””;””;””;””;””}

{=MIN(…)} portion: This would find the minimum of {10;7;””;6;””;””;””;””;””;””} which is 6. The starting position of number inside text.
Because we are finding multiple items, we need to array enter the formula to get correct result.
Finding the length of number
Once we find starting point, next we need to know the length of the number. There are many ways to do this. Depending on the variety in your input data, you can choose a technique that works best.
Approach 1 – counting number of digits in text
My first approach is to count number of digits in the text and use it as length. For this, we can break the text in to individual characters and then see if each of them is a number or not.
Assuming the text is in A1, the number of digits in it are,
=SUMPRODUCT(- -ISNUMBER(MID(A1,ROW($A$1:$A$200),1)+0))
MID(A1,ROW($A$1:$A$200),1) + 0 portion: This breaks the text in A1 in to individual characters (assumes the max length is 200) and then adds 0 to them.
At this stage, you have 200 values some of them numbers, others errors.
ISNUMBER(…) portion: This checks all the 200 values for numbers. After this, we will have 200 true or false values.
— ISNUMBER (…) portion: This converts the true, false values to 0s and 1s. (by double negating Excel will convert boolean values to number equivalents).
SUMPRODUCT(…) portion: This finally sums up all 1s thus giving us the number of digits in the text.
Does it work?
While this approach works well for some numbers, it fails in other cases. For example, a text like US $ 31330.00 has number portion with 8 characters (31330.00) where as our formula would say the length is 7 (because decimal point . is not a number and hence ISNUMBER() would give false for that).
So I had to move on to next approach.
Approach 2 – counting number of digits, commas & decimal points in text
The next approach is to count not only numbers, but also commas & decimal points in the text. For this, first I placed all the digits (0 to 9) and comma & decimal point in a range called as lstDigits.
Below formula counts how many of lstDigits are in text in A1.
=SUMPRODUCT(COUNTIF(lstDigits,MID(A1,ROW($A$1:$A$200),1)))
COUNTIF(lstDigits, MID(…)) portion: This checks how many times each of the 200 characters appear in lstDigits.
This would be an array of counts. For example {0;0;0;0;0;1;1;1;1;1;1;1;1;…} for US $ 31330.00, indicating that first 5 are not in lstDigits and then we have 8 in lstDigits.
SUMPRODUCT(…) portion: just sums all the numbers, hence we get length as 8.

Extracting numbers from text
Once we have starting position of number & its length, we can combine them in a MID formula to extract the number. Here is the result for our sample data set.
As you can see, this method works well, but fails in some cases like,
- European number formats (, for decimal point and . for thousands)
- Text with multiple numbers
Fortunately, in my data set, we had only a few incidents like these. So I have decided to manually adjust them than work out even more complicated formula.
Using Macros to extract numbers from text
As you can guess, we can use a simple macro (or UDF) to extract numbers from a given text. We will learn how to do this next week.

How do you Extract numbers from Text?
Often I deal with data like this. I use a mix of techniques. Apart from the one mentioned above I also use,
- getNumber() UDF to extract numbers from text (more on this next week)
- Use SUBSTITUTE to clear formatting (replace dots with empty spaces and commas with dots to convert from European format to standard format)
- Use VALUE to extract the number (works when number is shown as text)
- Use +0 to force convert numbers from text (works when number is shown as text)

Chandoo,
this is a really cool stuff what I use quite often. In addtion this method also could be a good choice to switch the reference type of the formulas from relative to absolute or vice versa. (just simply replace the $ in the same way).
Andras
@Andras: you are right, we can use find / replace to change references, reference types etc. Now, only if they had regex in find/ replace, we could so much more 🙂
@Tony Rose: Thank you. This is very useful and powerful feature. I even use it for cleaning up data. While formulas are good, they are not the solution for every problem. Often when I need more powerful cleanup / changing, I copy paste the stuff to text editors like notepad++ and then use their find/replace to do the dirty task.
What if i have to change the formula from ='Analysis'!C1 to 'Analysis 1'!C1?
I tried doing it using Find /Replace but could't. Encountered some errors.
And is there a way to change this using VBA???
Hi,
Did you ever get a reply to this?
Thanks
Ollie
to make your life easier, suggest you to avoid (Space) in worksheet names whenever possible. Consider (underscore) instead.
As the first formula wouldn't have the single apostrophes (since there's no space) need to include that in replace. So, search for:
Analysis
and replace with:
'Analysis 1'
This could be the most useful tips I've seen in a while. I use this all the time and can instantly change 400 formulas with a few clicks. Like so many other functions in Excel, I don't know what I would do without this one.

THANKS BRO
You, sir, are a god among men...
This is really cool. Your just save me hours of work. Thanks.
Thanks so much for this fix! It saved me tons of work. I'm muddling my way through and this really helped!
Oh... My... God!
This tip just saved me about 2 hours every month! I can't believe how easy it is to use. Now, can somebody tell me who I should call to get a refund for the previous 100 hours I spent manually changing formulas cell by cell?
Thanks so much!
THANK YOU!!!
THANK YOU!!!!
You saved me hours, I had a sheet that has more than 500 formulas, and i needed to replace the year in all of them, you saved me hours
Awesome info on replacing cell addresses in formulas. I have never heard about Ctrl+` before. Thank you!
I have something inside a formula like:
=sum(A1, A2*10) all over I now need to get rid of the *10 {=sume(A1, A2)} I thought to use the find replace trick above but with a blank in the replace but it then outputs just zeros. I thought I could trick it by doing *1 but then it just turns into =*1) with none of my references. Does anyone have an idea how to do this?
The Ctrl+ trick is cool.
@T
Instead of replacing with a blank try replacing
*10)
with
)
Thank you! This literally will save me hours and hours of time, and that's without losing my sanity in the process!
I have Sheet(1), Sheet(2), Sheet(3), etc ... Sheet(100).
Then there's a summary tab where I want to recap information on all those different sheets. Is there anyway to create a formula on the Summary tab to get ='Sheet(1)'!B$29 copied down for all 100 sheets without having to change each sheet # within the formula by hand?
@Brigitte
If you have a list of the sheet names in A2:A100
In B2: =INDIRECT("'"&A2&"'!$B$29")
Copy down
or if you don't have a list of the sheets names you can make it up on the fly
=INDIRECT("'sheet("&ROW()-1&")'!$B$29")
Copy down
Thanks for the suggestion. However, I copied your formula right back to my file and it didn't work. So I did it another way. I put the tab/cell reference in one cell and then did an =INDIRECT() to capture that information.
K2="'Sheet("&L2&")'!B$29" which has a value of 'Sheet(1)'!B$29
B2=INDIRECT(K2) which now has a value of 40 (contents on Sheet(1).
Thank you!!!!
Thank you ..
Hi, Out of all the formulae, I wish to replace the formula which has generated 0 value with blank space? I am unable to do it with find and replace function,
Please suggest.
Thanks.
Chandoo, you literally just saved me about 2 hours of work. I had a document with a daily report in two formats. The second formate just linked to all the appropriate cells in the other format (different sheets). This was 180 references that needed to be changed and I had to make this for a 4 week period (aka 28 different sheets at 180 references to change per sheet).
Thanks so much.
I have tried this way and without using the Ctrl-` formula view
Either way, I am trying to do something simple, but it won't let me.
I have a bunch of cells with a simple math formula like
=-(0.5*20)
various values in each cell, multiplied by 20
I simply want to change the multiplier globally from 20 to 25. But when I tell it to find *20 and replace it with *25, it replaces the entire cell contents with *25, rather than just replacing the *20 portion of the cell contents.
Can anyone assist with this? Seems so simple, but Excel isn't letting me do it.
Search/Replace 20 or 20) with a cell Reference eg A1 or A1)
Then put the value 25 in A1
By using a * in the search it replaces all the text

please help.
This is a great tool, does anyone knows an easiest way??
I'm working with a system that has over 59000 references... so every time the replace all is activated. I lose an entire day.
i actually needs to find cell number "D12" in column "D" and replace with Cell Number "B8" for example
find what = Cell Number "D12" John McNamara
find Where = in Column "D"
Replace with = Cell Number "B8" Bieber D'Souza
Replace Range = Column "D"
In which Sheet = All Sheets in Work Book (more than 100 Sheets)
Note: in every Sheet Cells Number "D12" & "B8" containing Different Employ Name but the find rang and replace rang are same in every sheet and find what cell number and replace with cell number are same also.
please help!
thank you. saved lot of time.
Thank you from the bottom of my heart!
Hi, I am trying to figure out how to use RE to find and replace several values in a column. Using find and replace does not work because of the values I am working with. I have a column with hundreds of rows that have a description of several operating systems and other info, which looks like this: Windows Server 2008 R2 Member Server Security Technical Implementation Guide; Windows 2008 Member Server Security Technical Implementation Guide; Solaris 10 10 SPARC SECURITY TECHNICAL IMPLEMENTATION GUIDE; and Windows Windows 2003 Member Server Security Technical Implementation Guide.
I need to be able to find and replace (or basically curtail the descriptions) to be Windows 2008 R2; Windows 2008; Windows 2003; and Solaris 10. BUT when I run find and replace with just *2008*, it finds every instance, including the ones with R2 at the end. I need it to only change the ones with 2008 to Windows 2008 and the ones that have 2008 R2 to Windows 2008 R2. I know it is possible, but I have no clue on how to write a macro to do this.
Thanks for your help,
Gerard
Wickedly efficient workaround. Excel really is a powerhouse program, all you have to do is dig into it. Ctl ~ exposes the formulas, and Ctl H allows for the multi edit. Brilliant, Chandoo!
