Research labs, teaching environments, and QA teams regularly deal with spectral data files locked inside proprietary formats. Without the right vendor software — which is often expensive and platform-specific — simply viewing a spectrum can be a roadblock. SpectralBench removes that barrier with a zero-install viewer that runs entirely in your browser.

Drag any JCAMP-DX, SPC, Bruker OPUS, or CSV file onto the workbench and get an interactive chart in seconds. SpectralBench parses the file on your machine — nothing is ever uploaded to a server — so your data stays private. Whether you need to quickly inspect an FTIR absorption spectrum or explore the metadata embedded in a legacy SPC file, the viewer gives you the tools you need without the overhead.
