Top 12 JavaScript CSV Projects

  • GitHub repo SheetJS js-xlsx

    :green_book: SheetJS Community Edition -- Spreadsheet Data Toolkit

    Project mention: Tips for Making a Popular Open-Source Project in 2021 [Ultimate Guide] | | 2021-11-12

    Maybe a story from a maintainer would help. To contextualize, the main SheetJS open source project has over 28K stars.

    tl;dr: the project involves "crowdsourced research" which benefits from popularity.

    The main social goal with the project is data preservation and integrity. Large-scale economic and political decisions are made from data and analyses in spreadsheets. For example, last year in the UK, COVID cases were underreported thanks to Excel minutiae

    Due to various corporate stratagems, the older data representations were intentionally obfuscated. To support Excel, many developers poked around at Excel files and guessed at the structures.

    In this environment, the biggest challenge is finding worksheets with random corner cases. These types of files are not easy to create and fuzzing has limited effectiveness. This is where open source and popularity come into play. The open source and JS nature of the project helps reduce testing friction ( runs in the web browser, no need to install anything) and encourage bug reports with test cases.

    There will always be "entitled users" and "low quality bug reports" but that comes with the territory. There are also meaningful issues and code contributions. Efforts at trying to prevent the low quality contributions also discourage higher quality contributions.
