Between 2024 and 2026, I built React components to navigate the Parquet and CSV files published in Source Cooperative, a catalogue of open datasets, published in Cloud-native formats. The project is led by Jed Sundwall.
For both formats, I adapted features and style of the open-source hyparquet demo, on which I had already worked a lot for Hyperparam.
For CSV files, I had to build a custom parser to be able to navigate into large files without fetching and parsing the whole file. I published this parser as an open-source library named cosovo, which I developed on my own time.
