    Why should I use DsExcel and SpreadJS together?

    Improved export speed

    Export large Excel spreadsheets to .sjs format, which is much faster than other formats.

    Minimized storage space

    Excel workbooks saved in the .sjs format have a smaller disk size. This reduces installation space by compressing JSON files, which are similar to the Excel XML structure.

    Compatibility with Excel

    The DsExcel API for .NET and Java allows you to easily convert Excel XLSX to SpreadJS .sjs files.

    Custom options

    Use the Open and Save options to choose whether to include styles, formulas, names, and empty cells when importing or exporting .sjs files.

    Generate JSON

    Convert SpreadJS or Excel spreadsheets to .sjs compatible JSON strings or streams.
