    Save memory and time with the lightweight API architecture. The more rows in the spreadsheet the faster our API is by comparison.

    Retain everything and lose nothing on the import or export. Documents for Excel supports pivot tables, comments, charts, conditional formatting, data validation, formulas, shapes and pictures, sparklines, and tables.
