For Finance & Accounting
Compare any two financial documents or spreadsheets and see exactly what changed — numbers, line items, totals. Every difference highlighted. Files stay on your device.
Use cases
Upload two versions of a budget spreadsheet and see every variance — by row, by column, by line item. No manual hunting for differences.
Compare the invoice you received against your purchase order. Catch price changes, added line items, or amended totals before approving payment.
Compare this month's report against last month's. See exactly what was restated, added, or removed at a glance — not line by line.
Privacy
Spreadsheets and financial documents are sensitive. We have no technical ability to see your files — all comparison happens locally in JavaScript inside your browser. There is no server receiving your data. This is not a policy promise — it is an architectural fact.
Compare Files works entirely in your browser. There is no server that receives, processes, or stores your file data. Not because we promise not to look — but because we architecturally cannot. All comparison logic runs locally in JavaScript.
Spreadsheet and document comparison unlocked with a one-time $9 payment. No subscription, no per-file fees.
