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.

I built a frontpage for personal blogs▲783
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.
