No re-upload neededThese tools accept .CSV - your file is handed over directly.
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
Many web forms, database import functions and hand-written scripts accept CSV only - a spreadsheet maintained in LibreOffice or OpenOffice Calc as .ods does not fit there without an extra step. This tool reads your .ods file locally and produces one matching CSV per sheet.
Each cell keeps the display exactly as the app shows it, for example a date in the familiar format rather than an internal number. Several sheets are automatically bundled into one ZIP package containing all the CSV files, so you do not have to download each one separately.
Worth knowing: a CSV only knows rows and columns of plain text - cell colours, borders and built-in charts from the ODS file are lost, and formulas are replaced by their last calculated result. That very reduction is exactly what makes the file usable for scripts and databases in the first place.

Limitations: Each cell arrives as plain text, exactly as the app displays it; formulas are replaced by their last result. Cell colours, borders and charts from the ODS file cannot be represented in the CSV format. Encrypted, password-protected .ods files are rejected.
No. The conversion runs entirely locally in your browser - nothing is sent anywhere.
Each sheet becomes its own CSV; you get them all bundled as a ZIP.
CSV stores values only - formulas become their computed result.
No, an encrypted file is rejected with a clear message. Remove the password in the source application first.
