Step 2: Automatic conversion
Rows and columns are read and written as CSV in a fraction of a second.

About the formats

What is ODS?

ODS is the spreadsheet format of the OpenDocument standard (ODF), an open, ISO-standardised format. It is the native format of LibreOffice Calc and Apache OpenOffice Calc. Like XLSX, an ODS file is a ZIP archive containing XML, with sheets, formulas, styles and charts. Microsoft Excel and Google Sheets can also open and save it.

Use ODS when you work with LibreOffice or when an open, vendor-independent format is required, as is common in public administrations. If your recipients mostly use Excel, XLSX avoids small formatting differences; for plain data exchange, CSV is enough.

What is CSV?

CSV (comma-separated values) is a plain-text format that stores tabular data, one row per line and fields separated by commas. It needs no special software: any text editor, spreadsheet application or database can read it. Because of its simplicity, CSV is the universal interchange format between databases, spreadsheets and other programs.

Use CSV whenever you need to move tabular data between systems, exporting a database, importing contacts or sharing a table with someone who uses different software. Choose CSV when plain, predictable data matters more than formatting.
