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)

This borders on Excel soft-cell...er, soft-core...porn. My favorite kind.
Wow, that is pimp-TASTIC! I have a question, as a VBA n00b: additional comment boxes stay plain unless I "run" the macro. Is there a way to change all comments, going-forward?
hi Chandoo, well, I like the macro approach. For those who don't like it, there is another way: just add the "draw" toolbar to the shapes toolbar (via Custom etc), click on "edit comment", click on the auto-shape and then choose "draw" drop-down, --> modify auto-shape --> then you even can have a heart or a banner (I like the horizontal banner in in purple :-)) . in excel 2007, you have to add this custom menu that you choose via Excel Options --> Custom --> it is called "change/ modify auto-shape"!!!
best,
@Chandoo. Great Post 🙂
@Tim : the way the macro is coded, it must be run very time.
@Community: If someone has an idea to perform it when opening an existing excel, it should be nice.
@Community: if someone has some code to revamp the commentboxes on all sheets, please share it. 🙂
@Microsoft Excel-progammers: some pimpoptions for the commentboxes should be great.
Cheerio
Tom
For the auto run, please add the codes in workbook:
Private Sub Workbook_SheetActivate(ByVal Sh As Object)
Call Comments_Tom
End Sub
Wow, that was a lot of fun... Thanks Tom!
@Jeff... Now, 5000 people know about your favorite porn... 😛
@Tim ... you can write an event to handle the new comments. I wouldnt recommend it as it is really painful. another option is to use the macro suggested by Yukikomi. It will update comments everytime you activate the sheet.
@laguerriere: very cool 🙂
@Chandoo ... Thanks! This is good stuff. I combined your tip with a tip from Mark O'Brien, then assigned it to a button on Excel 2010's Quick Access Toolbar, to format comments AS I add them. I also like how Mark's code saves me the trouble of backspacing my name out of new comments:
Sub AppendToExistingComment()
'Source: Mark O'Brien at http://www.mrexcel.com/forum/showthread.php?t=57296
Dim oRange As Range
Dim oComment As Comment
Dim sText As String
'Use object variable to hold range.
Set oRange = ActiveCell
'Use object variable for comment
Set oComment = oRange.Comment
'text to be added to the comment box
sText = InputBox("Type text to be added:", "APPEND TO COMMENT TEXT")
If Len(sText) = 0 Then End
'If Active Cell has a comment then append new text to the end of the comment text
If Not oComment Is Nothing Then
sText = oComment.Text & vbNewLine & sText
oRange.Comment.Delete
End If
'Add a comment with the contents of sText
oRange.AddComment sText
DoEvents
Comments_Tom
End Sub
Thank you very much for the code, it seems to be working for the most part; I am having a problem however. Once the routine makes the corrections to the comment, the comment becomes invisible. By invisible, I mean that when I highlight my mouse over it, nothing appears. However, when I right click the cell and click 'edit comment' then the comment becomes visible and I enter edit mode. Upon clicking out of the comment, it simply vanishes again. I've tried to fix this problem by adding a .shape.visible = msoTrue but then every comment is always visible. o_O please advise...
Thank you,
Nick
@Nick- That is because the font color of the comment is white and when you select the color of selection is also white hence you can not see anything. Try to change the color code in the routine to something else. would work
Thanks for that! The code works perfectly!

@ Chandoo - code works great and the comments look super cool. But I have ran into a small issue. In the comments, I am inserting pictures. When I run the macro, for all comments which already have pictures; pictures are deleted. Pls help me retain the pics in comments.

Hi Tom,
This looks really excellent. I am however relatively new to macros / VBA codes so having copy pasted your code in the Developer mode of an Excel file, what are the next steps to use them? Can you please help? Just to recap, I opened a blank Excel workbook, clicked on Developer, copy pasted the comments code and saved the file to the desktop.
Now how do I go about using it to add comments to an existing file? My apologies for asking a question which may be basic to you great geniuses, but I am not there yet and aspire to get there.
Many thanks for helping me with next steps that I need to take so that I can now use the code.

Dear Dave,
The best thing to do is to copy the macro in the personal.xls(x) file. The personal excel file will always be launched when you open excel so you can use it with every excelworkbook.
Read all about it on the page of Microsoft.
https://support.office.com/en-us/article/Copy-your-macros-to-a-Personal-Macro-Workbook-aa439b90-f836-4381-97f0-6e4c3f5ee566
Once you have the macro in the personal, you can 'call' the macro by the keyboardcombination 'alt+f8' and klik on the macroname.
Hope this clarifies the 'how to'. Good luck with your first steps in the wonderfull world of macro's.
Tom
Hi Tom,
Many thanks. I will try that out. Learning is fun and learning this stuff is even more amazing.

There is a line 'Dim LArea As Long' which does not appear to be used. Have I missed something?
Dear Gary,
Correct the 'Dim LArea As Long' is indeed not relevant and can be deleted.
Tom
Excellent hack!
For some reason when I opened my file after using LibreOffice Calc, all comment boxes had changed to some arrow shape.
So this macro helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
I used it with the following attributes to get back old style comments:
It helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
.Shape.AutoShapeType = msoShapeRectangle
.Shape.TextFrame.Characters.Font.Name = "Calibri"
.Shape.TextFrame.Characters.Font.Size = 10
.Shape.TextFrame.AutoMargins = True
.Shape.TextFrame.AutoSize = True
Thanks a lot!
This was helpful, thank you
I think this is among the most significant
information for me. And i am glad reading your article.
But wanna remark on some general things, The site style is great,
the articles is really great : D. Good job, cheers
Is there code to add to this that will format a particular part of the comment (i.e. make the last sentence in the comment bold and in italics)?
This is fantastic!
How would I add auto-sizing to it?
I tried adding this:
.Shape.AutoSize = True but it gives me an error and as a novice at VBA I can't figure it out.
.Shape.TextFrame.AutoSize = True
Hello I am so glad I found your web site, I really found you by accident,
while I was browsing on Bing for something else, Nonetheless I am here now and would
just like to say thanks a lot for a remarkable post and a all round entertaining blog (I also love the theme/design), I don’t have time to
read it all at the moment but I have book-marked
it and also added in your RSS feeds, so when I have time I will be back to read a lot more,
Please do keep up the fantastic work.
This is GREAT!
How should the code be changed in order to tun once for all worksheets in a workbook?
