Renamed sheets, ranges, or files
Code still points at an old sheet name or workbook path. Excel throws a run-time error when that object is missing.
Fix a Broken Excel Macro
Excel macro repair for Microsoft Excel VBA when an Excel macro stopped working, throws errors, or broke after a file, PC, or Office change.
Can someone fix my broken Excel macro?
Yes. You can hire someone to fix a broken Excel macro when the code throws a VBA error, runs the wrong result, or fails after a change. Send the file and the error. I diagnose the break, repair the code, test it, and return the workbook with a short note on what changed. This Excel VBA debugging service is for existing macros, not a full rebuild.
Why Excel macros stop working
A macro is a recorded or written VBA routine stored in a workbook or add-in. It usually fails because something around the code changed, not because Excel forgot how to run it.
Missing library references
A Reference in the VBA editor points to Outlook, ADO, or another library missing on the new PC. Compile fails before the macro runs.
32-bit to 64-bit Office
Old Declare statements need the PtrSafe keyword and updated pointer types for 64-bit Excel. Without that, the project will not compile.
Macro security and Trust Center
The Trust Center is Excel's macro security settings. If macros are disabled or the file is untrusted, the code never starts.
Data layout changed
Columns moved, headers changed, or blank rows appeared. The macro keeps old assumptions and returns wrong results or errors.
Excel version or companion apps
Code that called Outlook, another workbook, or an .xlam add-in breaks when those pieces move, update, or stop loading.
Errors people actually see
Run-time error '9': Subscript out of rangeRun-time error '1004'Run-time error '13': Type mismatchRun-time error '91': Object variable or With block variable not setCompile error: Can't find project or libraryCompile error: The code in this project must be updated for use on 64-bit systems.
VBA means Visual Basic for Applications, the language behind most Excel macros. The VBA editor holds modules, references, and Declare statements. A reference is a linked library the project expects. PtrSafe marks a Declare as safe for 64-bit Office.
What we fix
Repair focuses on macros that already exist. The goal is a working button again, with notes your team can keep.
Runtime and compile errors
Messages that stop the macro mid-run or stop it from compiling in the VBA editor.
Wrong results without a crash
The button still runs, but totals, exports, or emails are wrong after a layout or logic change.
Slow macros
Code that used to finish quickly and now crawls through rows, sheets, or file loops.
New Excel version or new computer
A macro that worked on the old PC and fails after a Windows, Office, or 64-bit move.
Add-ins that stopped loading
.xlam add-ins that no longer appear, fail on open, or break after an Office update.
Inherited macros with no notes
Legacy Excel macro code left by someone who is gone, with no map of what each module does.
Personal macro workbooks and Outlook automation are in scope when they are part of the failure. ActiveX controls that only exist on Windows are called out when Mac is involved.
How I fix a broken Excel macro
The process is diagnose first, then edit. Guessing in the live file is how data gets hurt.
You send the file and the error
Share the .xlsm or .xlam, the exact message or screenshot, and what the macro should do. Note when it last worked and what changed.
Reproduce the problem
{{CONFIRM: Excel macro repairs are reproduced on a copy of your workbook before any production change}}. I recreate the failure with your steps before editing code.
Find the cause
I check references, Declare statements, sheet names, Trust Center blocks, and the line that throws. The goal is the real break, not a guess.
Fix and test
I patch the code and retest against your sample data or the scenario you described. Edge cases that caused the failure stay in the test pass.
Hand back with notes
You get the repaired file and a short note on what changed. You own the code. {{CONFIRM: post-fix support window for Excel macro repair engagements}}
Chat-style tools can suggest syntax for a short snippet. They cannot open your .xlsm, walk linked files, or prove the totals still match. When the macro is undocumented or the data matters, a person with the file is the safer path.
Repair or rewrite?
Fix the macro when the design still fits the job. Rewrite when the design is the problem.
Repair is enough when one module fails, a reference is missing, a sheet was renamed, or Declare statements need a 64-bit update. Rewrite is better when many modules share brittle layouts, nobody can describe the intended behavior, or you need new features the old structure cannot hold. Rebuilds are scoped under VBA development, not as a silent expansion of a small repair quote.
What to send for a fast answer
Clear inputs cut the back-and-forth. This checklist helps me see the break before the call.
- The workbook or add-in file (.xlsm, .xlsb, or .xlam)
- The exact error text or a screenshot of the dialog
- What the macro should do in plain words
- When it last worked
- Excel version and whether you are on Windows or Mac
- What changed since: new PC, Office update, renamed sheets, new data layout, missing companion file
Remove or mask sensitive rows if you must. Say what you removed so test results stay honest. {{CONFIRM: file transfer and confidentiality terms for Excel macro repair}}

Excel macro repair FAQ
Direct answers for owners who need to repair broken Excel macro code without a full rewrite.
Why did a macro that worked yesterday fail today?
Something around the code changed. Common triggers are a renamed sheet, a missing reference, a Trust Center block, a 64-bit Office install, or data in a new layout. The code did not age overnight. The inputs around it did. Finding what changed is the first repair step.
Can you fix a macro someone else wrote?
Yes. Most repair work starts on code I did not write. I read the modules, recreate the failure, and fix the break. Undocumented legacy Excel macro projects are common when the author left and nobody kept notes. A clear error message and sample data still help even when the original author is gone.
Why does a macro work on one computer but not another?
The second PC often has a different Excel bitness, missing library references, stricter macro security, or a different folder layout. Declare statements that lack PtrSafe fail on 64-bit Office. That is a common Excel VBA debugging service case when a macro works on an old computer but not a new one.
Is it better to repair or rewrite the macro?
Repair when the design still matches the job and the break is local. Rewrite when the code is fragile across many modules, depends on brittle sheet layouts, or needs features the old design cannot hold. Rebuilds belong under VBA development.
How much does Excel macro repair cost?
Cost follows how hard the break is to reproduce, how many modules are involved, and whether 64-bit updates, add-ins, or Outlook automation are in play. Quotes follow the same advisory and fixed-price patterns on the pricing page. This page does not list a separate repair rate.
Can AI tools fix my Excel macro?
They can help with simple syntax hints. They cannot see your workbook, your live data, your missing references, or your other files. A wrong edit can damage results. For undocumented macros and data you cannot risk, hire someone to fix my Excel macro with a tested file handback.
Do Excel macros work the same on Mac?
Excel for Mac can run many VBA macros in macro-enabled workbooks, but security prompts and some Windows-only features differ. Macros that call Windows APIs or certain ActiveX controls often need Windows desktop Excel. Say which platform fails when you send the file.
Official notes: Microsoft Learn on the PtrSafe keyword, and Microsoft Support on Excel macro security settings.
