FOR ACCOUNTANTS
Spreadsheet reconciliation for accountants. No AI. No cloud uploads. No VLOOKUP.
Deterministic CSV and Excel reconciliation that runs in your browser. The same two files always produce the same result — so when an auditor asks why a row matched, you can point at the exact column and the exact rule.
The three no's
No AI
Microsoft's own Copilot docs warn that AI totals can hallucinate. SheetPair uses deterministic rules — same inputs, same outputs, every time.
No cloud uploads
Files under 50,000 rows are processed entirely in your browser. Your financial data never hits a third-party server.
No VLOOKUP
Upload, map columns once, reuse the config every month. No formulas to maintain, no breakage when a schema drifts.
How it fits your monthly close
- 1. Export — pull the ledger and the bank file out of your accounting system.
- 2. Map once — set the key and compare columns the first time, save the mapping.
- 3. Reuse — next month, drop in the fresh files and the mapping applies automatically.
Why finance teams pick it
- • Deterministic results — same input, same output.
- • Browser-only processing for files under 50,000 rows.
- • No third-party AI calls with your financial data.
- • Full audit trail — every match traces to a column and a rule.
Privacy
Your data never leaves your browser
SheetPair processes files entirely on your device using Web Workers. Your spreadsheets are never uploaded to our servers, never stored in a database, and never sent to a third-party AI model. Close the tab and the data is gone.
For files over 50,000 rows that need server-side processing, data is encrypted in transit and auto-deleted within 24 hours. No AI round-trips.
Frequently asked questions
- What's the best Excel reconciliation tool for accountants in 2026?
- Depends on scale. For enterprise close, BlackLine or FloQast. For recurring monthly reconciliations that don't justify a six-figure platform, SheetPair: browser-based, no install, deterministic matching, starting at $19/month.
- Why not just use AI or Copilot to reconcile spreadsheets?
- Microsoft's own Copilot-in-Excel documentation warns that AI-generated numeric totals can be wrong. For a bank reconciliation, one hallucinated total is a compliance problem, not a typo. SheetPair is deterministic — the same two files always produce the same result, and you can show an auditor exactly why each row matched.
- Do I need to replace VLOOKUP with Power Query?
- Power Query works but has a steep learning curve and breaks when source schemas drift. SheetPair handles the same reconciliation in three clicks: upload, map, review. Power Query is still the better tool for complex ETL — not for monthly recurring reconciliation.
- Is SheetPair suitable for audit trails and compliance?
- Every match is traceable to a specific column mapping and rule (exact, numeric tolerance, or fuzzy). Results can be exported to CSV or Excel for attachment to workpapers. No AI is involved, so there's no 'why did the model decide this?' problem.
- Do I need a Microsoft 365 Enterprise license to use SheetPair?
- No. SheetPair is a standalone web app. It works with CSV and Excel files exported from any source — QuickBooks, Xero, Sage, standard Microsoft 365, or Google Sheets.
