Synkronizer alternative
When the job is reviewing changes, not merging them
Synkronizer is great at comparing and merging two sheets inside Excel. SheetDelta is built for teams who need to review, approve, and prove changes across SharePoint, with an audit trail. It doesn’t auto-merge workbooks, on purpose.

Where Synkronizer is strong, and who should pick it
Synkronizer is a serious tool that does something SheetDelta deliberately doesn’t: it compares two sheets and then merges or updates the data between them, inside Excel. It’s praised for SOX reconciliation and for the hours it saves doing that by hand. If your core job is comparing and merging data inside Excel, it’s purpose-built and an excellent fit. Here’s where it does well:
Comparing and merging in one pass
Synkronizer’s core strength is comparing two sheets and then merging or updating values between them, right inside Excel. If that’s your job, it’s purpose-built for it.
Working inside Excel
It runs as a Windows Excel add-in, so the compare and the fix happen in the workbook you already have open. No exporting, no second app.
SOX-style reconciliation
It’s well-regarded for SOX auditing and for the time it saves reconciling two versions of a sheet by hand.
A perpetual license
Around €99 professional or €199 developer, paid once. The developer edition adds command-line and automation for repeatable runs.

Synkronizer details from its own site, June 2026: Windows Excel add-in, perpetual license, developer edition adds command-line automation. SheetDelta's Combine merges on the hosted platform, group by group with your approval, and never writes into an open Excel session. Details change over time, so check the current product pages.
Both merge. The difference is where, and what happens first
Synkronizer merges at your desk, inside Excel, with the file open in front of you. That is a good place to reconcile data, and it is what the tool is built for.
SheetDelta’s Combine merges on the hosted platform, after review. It works from the common ancestor of the two versions, proposes each change it would carry across, grouped into formulas and values, formatting, validations, comments and whole sheets, and writes nothing until you approve the group. Then it checks the file it produced against what it intended and fails closed rather than handing you one it cannot verify. We publish what is checked, what is not, and what happens when it fails.
Pick on the surrounding job: reconciling two sheets by hand, or carrying two people’s work together with a record of who approved what. The two can sit side by side.
SheetDelta’s wedge
The review, audit, and team layer that a single-seat in-Excel merge tool isn’t built to provide.
Review and prove, not merge
SheetDelta is for teams who need to see, discuss, and approve a change before it ships, then prove later that it was reviewed. Synkronizer is for changing the data. Different jobs.
No install, cross-platform
Compare in the browser on Windows, Mac, Linux or ChromeOS, with no Excel required. Synkronizer is a Windows Excel add-in.
A team workflow, not a single seat
The hosted platform watches SharePoint, anchors comments to the exact cell, requires sign-off, and keeps an audit trail. Synkronizer is a single-user, in-Excel tool.
Git and CI when you need it
A local git diff integration and a GitHub Action that puts the same readable diff onto pull requests are built but not yet publicly released. Synkronizer’s developer edition has a command line, but no hosted Git or review trail.
