Kimi Xlsx

This is a heavyweight spreadsheet tool that goes beyond basic CSV exports. It's built around openpyxl and pandas for Python-based Excel generation, but the real differentiator is the KimiXlsx CLI that validates your output before delivery. It catches formula errors, detects implicit array formulas that work in LibreOffice but break in Excel, and includes a pivot command that uses pure OpenXML SDK for programmatic PivotTable creation. The validation step is mandatory, which is actually refreshing since it prevents you from shipping files that won't open in Microsoft Excel. If you're generating complex spreadsheets with formulas, charts, or pivot tables programmatically and need them to actually work across different Excel versions, this handles the edge cases you'd otherwise debug manually.
