Hosted platform · Closed beta
Excel review your whole team can trust
SheetDelta watches the SharePoint or OneDrive files you already use, shows every change and who made it, and lets your team comment, approve, and sign off — with a full audit trail behind it.
Now in closed beta — join the waitlist for early access. The free web tool and desktop app are available today.
From “what changed?” to “signed off” in four steps
Connect your files
Point SheetDelta at the SharePoint or OneDrive library your team already saves to. No migration, no new place to save things.
It watches for saves
Every time someone saves a new version, SheetDelta compares it against the last one automatically. Nobody has to remember to upload.
Review what changed
See changed formulas, values, sheets, and macros down to the cell — with the author attached. Comment on a cell, request changes, sign off.
Keep the trail
Every version, comparison, comment, and approval is retained as an audit trail you can export when finance, risk, or an auditor asks.
Nothing to change about how your team works
Most version-control tools for Excel make you push files to Git or drag every version into an upload box. Finance and operations teams won’t do that, so the tool goes unused. SheetDelta watches the SharePoint or OneDrive library your team already saves to — so the review layer arrives without a single change to anyone’s habits.
What you get
SharePoint & OneDrive cloud-watch
The differentiator: it watches the files your team already keeps. No “upload every version,” no moving to Git.
Cell-anchored comments
Threaded discussion attached to the exact cell or range that changed — not a comment box bolted onto the whole file.
Sign-off & approvals
Require one or more distinct approvers, block self-approval, and resolve open comments before a change is trusted.
Block-until-approved gate
Team PlusFor the files that matter most, hold a risky change until it’s reviewed — by reverting or staging it.
Content checks
Team PlusCatch formula-to-value overwrites, edits inside locked ranges, and control totals that no longer foot.
Audit-trail export
A complete, exportable record of who changed what, when, and who approved it — built for regulated workflows.
Built for the “we already have SharePoint” conversation
SharePoint is a great backup. It just can’t tell you what changed inside the file.

Easy by default, strict where it matters
Review is a single dial, set per workbook or per project. Start at the easy end in minutes and slide right as the stakes go up.
Track-only
Versions, comparisons, and notifications. No review object — just a clean history.
Observe
Post-hoc review with optional approvals. Never blocks anyone.
Four-eyes
Distinct approvers, resolve-comments, and CODEOWNERS-style routing.
Gate
Block until approved, with content checks and write-back. For control files.
