Switched from LibreOffice to Excel and needed to convert hundreds of ODS files to XLS — this tool handled the entire batch without a single corrupted file.

ODS to XLS conversion worked correctly for all our financial templates. A couple of conditional formatting rules didn't transfer, but all data was intact.

Convert ODS to XLS — Frequently Asked Questions ▼

What is the difference between ODS and XLS?

ODS is the open-standard XML spreadsheet format used by LibreOffice; XLS is Microsoft Excel's binary format from the Excel 97–2003 era. Both store the same tabular data, but XLS is required by older Excel installations and some legacy systems.

Should I convert to XLS or XLSX?

Use XLS for compatibility with Excel 97–2003 and legacy systems. Use XLSX for compatibility with Excel 2007 and newer, Google Sheets, and modern BI tools. XLSX supports more rows (1,048,576 vs 65,536) and is the current standard.

Will LibreOffice formulas work after converting to XLS?

Formulas that use functions supported by both LibreOffice and Excel (SUM, IF, VLOOKUP, etc.) are preserved and will calculate correctly. Formulas using LibreOffice-specific functions may not work in older Excel versions.

Does the conversion support multiple sheets?

Yes. All worksheets in the ODS file are converted to separate sheets in the XLS workbook. Sheet names and tab order are preserved.

What is the row limit in XLS format?

XLS (Excel 97–2003) supports a maximum of 65,536 rows and 256 columns per sheet. If your ODS file contains data beyond these limits, convert to XLSX instead, which supports over one million rows.

Are charts and graphs preserved in the XLS output?

Basic charts created in LibreOffice Calc are converted to Excel chart objects in the XLS output. Complex or custom chart types may render slightly differently due to format differences between the two applications.

How do I convert a large ODS document library to XLS for distribution?

Total Excel Converter ($29.90) handles batch conversion: TotalExcelConverter.exe C:\ods_folder C:\xls_output /ConvertTo xls /ProcessRecursively. It processes entire folders in one command-line operation.

Preserves formulas and cell values — data and calculations are correctly converted from ODS to XLS structure
No LibreOffice required — convert the file online without installing any office suite
Instant download — upload and receive the converted XLS file in seconds

What Is ODS?

ODS (OpenDocument Spreadsheet) is the XML-based spreadsheet format of the OpenDocument standard (ISO 26300), used natively by LibreOffice Calc, Apache OpenOffice, and Google Sheets. While ODS is an open standard, it is not natively supported by older versions of Microsoft Excel and may trigger compatibility warnings even in newer Excel versions.

What Is XLS?

XLS is Microsoft Excel's legacy binary spreadsheet format (Excel 97–2003, BIFF8). It is supported by every version of Excel ever released and by most third-party spreadsheet tools. XLS has a row limit of 65,536 and a column limit of 256, which covers the vast majority of real-world spreadsheets. It remains the most compatible format for sharing with users on older Excel installations.
