We analysts like to compare. If you ever want to keep an analyst busy, just give her 2-3 options. She won’t return to your desk until the cows come home. My wife uses this trick all the time. Picture this:

[In late 2013]
Me: I want to buy a new phone
She: Do you want Nexus 5 or Galaxy S5 or iPhone 5s?

Its late 2014 and I am not done comparing.

So today, let’s talk about an interesting comparison scenario.

Comparing by letter or word

Imagine you are looking at 2 lists like this and you want to know where items differ. Not which items, but where.

Compare 2 lists of data and highlight mismatched letters or words in Excel - How to?

That means, you want to know which letters or words in each line are different.

VBA to the rescue

Unfortunately, none of the standard features of Excel (formulas, conditional formatting, pivot tables etc.) can help us with this situation. But we don’t have to give up. We can use a simple VBA macro to instantly compare 2 lists and highlight mismatched letters or words.

A quick demo of our comparison macro:

Compare two texts in Excel and highlight unmatched letters or words using VBA Macros - Demo

How does this macro work?

When you set out to create macros like this, the first step is to define basic algorithm (logical steps in plain English). To compare 2 sets of data, we need to do below:

  1. For each item in list 1
  2. Get corresponding item in list 2
  3. If they don’t match
  4. For word match
    1. For each word in first text
    2. Get corresponding word in second text
    3. Compare
    4. If not matched, highlight in red color
    5. Repeat for other words
  5. For letter match
    1. Find the first mismatched letter
    2. Highlight all the letters from that point in second text
  6. Repeat for next item in list 1
  7. Done

Once you write down this logic, we simply go ahead and implement it in VBA code.

The exact workings of the macro are somewhat complex. So I made a video explaining how the code works & what it can do. Please watch it below.

Do you compare lists like this?

Every now and then, I end up having a situation where I need to compare by letter or word. I find VBA macro based solution to be perfect for this.

What about you? Do you compare lists? Where do you struggle with such comparisons? How would you use this macro? Please share your thoughts & tips in comments.

    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).

    • Chandoo says:

      @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.

      • Sonia says:

        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?

          to make your life easier, suggest you to avoid (Space) in worksheet names whenever possible. Consider (underscore) instead.

          • Luke Moraga says:

            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'

    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! 

  9. Bilal says:

    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

  10. Elliot says:

    Awesome info on replacing cell addresses in formulas. I have never heard about Ctrl+` before. Thank you!

  11. T says:

    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.

  12. Peter says:

    Thank you! This literally will save me hours and hours of time, and that's without losing my sanity in the process!

  13. Brigitte says:

    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?

    • Hui... says:

      @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

      • Brigitte says:

        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 ..

  15. Niharika says:

    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.

  17. Kevin says:

    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.

  18. Brian says:

    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.

    • Hui... says:

      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

    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.

  23. sadaqat says:

    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.

  26. Gerard says:

    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!
