Parse. View. Split. Transform.

All in your browser.

EDI Paisan is the modern way to work with healthcare EDI files. View 837 claims, 835 remittances, 270/271 eligibility, and 277CA/999 acknowledgments instantly, split large files with surgical precision, and generate EDI from spreadsheets.

File contents are never uploaded. We record the filename, size, SHA-256 fingerprint, envelope counts, and — for 837s — control numbers. The same when you continue as a guest. Crash reports may include a filename; we remove those on a best-effort basis. Privacy policy
