How to convert SPC files to ASCII without original spectroscopy software? IR and Raman spectroscopy are typically saved in *.SPC files (chemical/x-galactic-spc), which are binary files. Collected data is save to SPC files by default, but can be exported to txt (ASCII) files.

I now have original SPC files and the original spectroscopy software is not available. Is it possible to somehow read those files with some other (generic?) software?
If you don't mind Python on the command line, there's an spc converter on Github.

While the trial version of the GRAMS Suite 9.2 is available with a 30 days license, it seemingly doesn't work with any data but the samples provided with it and therefore isn't suitable for your purpose :(
