You can recalculate Excel formulas and check for errors in an xlsx file through zero-error recalculation and deterministic Office document validation. This verifies document integrity and recompute formulas to ensure your workbook contains no hidden errors.

LibreOffice and openpyxl work together to convert CSV and TSV files into polished xlsx workbooks. This combination handles opening, reading, and creating tabular documents while applying necessary formatting and preserving template conventions.
