Phone-safe limits: inspect 10,000 selected items; read up to 2,000 CSV or ZIP files; ignore unsupported items without reading them; 4 MiB per raw CSV; 24 MiB per Master or ZIP; 32 MiB per batch or expanded archive. A session is committed only when its complete recovery output also fits 24 MiB.
Ready for files.Your reports are not uploaded or saved after this page closes.

Built for recovery

Nothing gets flattened. Nothing gets guessed.

Lossless originals

The original bytes are stored in the master, so line endings, quotes, column order, and notes survive.

Future-site recognition

Current sites use structural fingerprints; new Mel's CSV Contract sites register automatically without filename guesses.

Future-safe quarantine

An unfamiliar future CSV is preserved and flagged instead of rejected or silently misfiled.

No hidden background state

The interface always loads fresh. Reports stay only in the current page until you save them.

Clear this working session?

This removes the reports from this page only. Your original files and anything already downloaded stay untouched.
