Reconcile — compare two data sources

How to use / tips

Load a source into A and B: choose a file, drag & drop, or click a panel and paste (screenshot, a table copied from a web page, or CSV text).
Multi-sheet Excel files: pick the sheet first. If the parsed first row isn't the header, change "Header row".
Auto-map pairs columns with matching names. Mark 1+ pairs as 🔑 Key (row identity); the rest are compared as values.
Tolerance ignores small numeric differences (e.g. rounding). The Dates option equates 3/4/2025 (US) with 04/03/2025 (EU).
Screenshots and scanned PDFs are OCR'd in-browser; the first OCR downloads the English model (~10 MB) from a CDN.
Large files (100k rows): give the page a few seconds; the report download always contains the full data.
