Convert ODT to XLS
What is ODT?
ODT
ODT stores flowing text with formatting in OpenDocument XML format. Spreadsheets store structured data in calculable cells with formulas. Documents contain narrative text; spreadsheets contain tabular data. Converting document to spreadsheet requires restructuring content manually—that's data extraction, not format conversion.
- ODT preserves document structure with text, formatting, and layout information
What is XLS?
XLS
XLS is Excel's legacy binary format using BIFF (Binary Interchange File Format) within OLE compound document structure. Stores worksheets, formulas, formatting, charts, and macros. No compression—larger files than XLSX. Maximum 65,536 rows and 256 columns per sheet. Gradually replaced by XLSX since Office 2007 but widely compatible with older systems.

Yes. Batch mode supports 3 .odt files (free) or 20 files (premium). Each .odt converts to .xls separately with preserved filenames and quality.
