Use cases

For finance teams and accountants.

1
Invoice discrepancy checks

Compare the invoice you received against your purchase order. Catch price changes, added line items, or amended totals before approving payment.

2
Budget vs actuals

Upload two versions of a budget spreadsheet and see every variance — by row, by column, by line item. No manual hunting for differences.

3
Monthly report revisions

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

Financial data never leaves your device.

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.

Your files never leave your device. Ever.

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.

Why no AI

No AI means no hallucinations.

Compare Files uses a deterministic, logic-based engine — not a language model. It reads both files and reports every change that is actually there. It can’t summarize away a deleted line, invent a difference that isn’t in the file, or “mostly” get a number right. What you see is exactly what changed — nothing added, nothing missed. For reconciliations, that means no AI mis-summing a total or rounding a figure away.

Private

Your files never leave your device. Everything runs in your browser — no uploads, nothing stored.

Certain

No AI, so no hallucinations. A deterministic engine reports every real change and never invents one.

Fast

No upload, no server wait. Comparisons run locally and keep working offline once the page has loaded.

FAQ

Common questions.

Can I compare a PDF invoice against a purchase order to verify line items?

Yes — upload PDF or DOCX documents side by side to verify that invoice amounts, quantities, and terms match the original purchase order. Catching a discrepancy before payment approval prevents overpayment and simplifies your audit trail.

Can I compare two versions of an Excel budget to catch what changed?

Yes — upload two .xlsx or .xls files and immediately see which line items changed, which rows were added or removed, and where values differ. Budget version reconciliation that used to take an hour of manual scanning takes seconds.

How does spreadsheet comparison handle large financial files?

Comparison runs in your browser using your device's processing power, so performance scales with your machine rather than a server limit. Most financial spreadsheets — including multi-row budget files and monthly reports — process in seconds.

Is financial data uploaded to any server during comparison?

No — all spreadsheet and document comparison is entirely local to your browser. Budget figures, invoice amounts, and vendor details never leave your device and are never stored or transmitted anywhere.

What does financial document and spreadsheet comparison cost?

Spreadsheet comparison (CSV, Excel) and document comparison (PDF, DOCX) are included in Pro — €9.99/mo, no per-file fees and no usage limits.
