Instrument file compatibility

Find your instrument. See the formats we can read.

FTIR.fun currently supports 36 input-format families. Vendor names below help you find the relevant formats; uploaded files are also checked to confirm that they contain readable spectrum data.

CSV · EXCEL · JSON

Tables & numerical data

.csv.dat.dpt.asc.txt.tsv.tab.xlsx.xls.ods.json

General numerical tables and spreadsheets with a validated spectral x/y structure.

A familiar extension does not always mean the file contains FTIR data.

Some scientific file types are used for infrared, Raman and other measurement modes. FTIR.fun checks the file contents and will report files that do not contain a usable FTIR spectrum.

Multi-spectrum files stay multi-spectrum.

Files containing multiple spectra are not silently reduced to the first curve. Choose the spectrum you need for single export, or use batch conversion when you want to retain multiple valid spectra.

Available metadata is preserved where possible.

Converted results retain the spectrum data and available metadata that can be read from the source file. If some vendor-specific information cannot be converted, the result will show a warning.

Your file is not listed?

Use Nonstandard Format Help instead of renaming the file, so the original instrument data stays intact.

Need many files converted?

The batch converter processes mixed supported inputs in one job and provides a clear summary of files that could not be converted.
