Microsoft Spreadsheet Compare alternative

The compare tool you’re looking for — on Mac, the web, and any Office plan

Microsoft Spreadsheet Compare does a real job, but it’s buried in specific Windows editions and missing from most of them. SheetDelta does the same job in your browser, free, with no special license.

Why you can’t find Spreadsheet Compare

It’s not hidden in a menu — it’s a separate Windows app that only ships with certain Office editions. If your plan doesn’t include it, searching the Start menu turns up nothing, and there’s no standalone download. Here’s roughly where it lives:

  • Office Professional Plus (2016–2021)
  • Microsoft 365 Apps for enterprise
  • Microsoft 365 Business Standard / Premium
  • Office Home & Business / Home & Student
  • Excel for Mac
  • Excel for the web

Microsoft’s edition lineup changes over time — check your own install. The point stands: access depends on your license, and it’s Windows-only.

Frequently asked questions

Is Microsoft Spreadsheet Compare free?
It’s bundled with certain Office editions rather than sold separately — so it’s “free” only if you already have the right edition installed on Windows. If you don’t, there’s nothing to download. SheetDelta’s web tool is free for everyone, on any OS.
Which Office version has Spreadsheet Compare?
It ships with Office Professional Plus and Microsoft 365 Apps for enterprise on Windows. It’s commonly missing from Business Standard/Premium, Home editions, Mac, and the web — which is why so many people go looking for it and can’t find it.
Can I compare spreadsheets on a Mac or online?
Not with Microsoft’s tool — it’s Windows desktop only. SheetDelta runs in any modern browser, so you can compare workbooks on a Mac, a Chromebook, or the web with nothing installed.
Is SheetDelta as accurate on hard cases?
Spreadsheet Compare tends to get noisy when rows are inserted or deleted — reporting a deleted row and an added row instead of the real change. SheetDelta aligns the sheets first and reads formulas as logic, so structural edits stay readable. For .xlsb, charts, pivots, and the deepest analysis, use the desktop app.
