Convert to XLSX
XLSX is Microsoft Excel's default format, supporting styles, formulas and multiple worksheets โ the standard for office data exchange. This group converts CSV and JSON data plus ODS and XLS workbooks to XLSX โ 4 conversion directions.
Output is a single-worksheet workbook with inferred data types; source formulas resolve to their cached values and styles are not migrated. Legacy XLS (BIFF8) files upgrade cleanly to the modern format.

JSONโXLSX
Generates an XLSX workbook from JSON object arrays with key names as headers, delivering API responses as editable reports.
ODSโXLSX
Converts ODS to XLSX, handing LibreOffice spreadsheets to Microsoft Excel users for further editing.
XLSโXLSX
Upgrades legacy XLS (BIFF8) to XLSX (OOXML), migrating pre-2003 spreadsheets into modern Office environments.
