The library cleaning pipeline is implemented in matchms. By extending the package, we thereby reuse existing functionality (e.g., loading mass spectra of diverse formats and standardizing metadata fields) saving implementation time and fostering collaboration. Matchms has an increasing active user base, a team of multiple developers, and a high standard for code quality. We expect that the here described developments will further stimulate its use throughout the metabolomics community and the mass spectrometry community in general.
