Native FTIR data

Professional FTIR format converter

Upload one original instrument spectrum, inspect the parsed curve and key metadata, then download CSV, JCAMP-DX or canonical JSON. The page uses deterministic format readers and does not send the spectrum to an LLM.

Preservation contract The canonical result keeps the complete parsed x/y arrays, a normalized metadata view, the parser-exposed raw metadata, source format, SHA-256 provenance and explicit warnings. CSV and JCAMP-DX carry the same metadata envelope for FTIR.fun round-trips.

Supported input families

One workflow for instrument data

The converter is separate from Image → CSV: it expects digital spectrum data and reports what the reader could preserve.
