What it does

Deterministic CSV and Excel reconciliation. Upload two files, map key columns, and see every match, difference, and missing row in seconds. No AI in the match path — same files always produce the same result. Auditable and reproducible. All processing runs in your browser via Web Workers, so your data never leaves your machine. Exact + Jaro-Winkler fuzzy + numeric tolerance matching. Export to CSV or Excel. Free for 3 comparisons/month, up to 1,000 rows. No signup.

Deterministic CSV and Excel reconciliation. Upload two files, match records by key, and find discrepancies in seconds. Free for 3 comparisons/month.

No AI guessing, no hallucinated totals, no prompts. Deterministic CSV and Excel reconciliation that shows what's matching, what's different, and what's missing. Upload two files and see matched rows, differences, and missing records in seconds. Every difference is highlighted at the field level so you can spot exactly what changed. Download results as CSV or Excel — filtered by matched, diffs, or unmatched. Drop your CSV or Excel files. Your data stays in your browser — nothing gets uploaded to a server. Tell SheetPair which columns to match on (like Invoice # or Account ID) and which to compare (like Amount or Date). See matched rows, differences, and missing records instantly.

  • With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
