Applications that open .ods files
ODS is the universal open-standard spreadsheet format — supported everywhere.
LibreOffice Calc
Native format — opens instantly with full formatting, formulas and sheet tabs. Free on Windows, Mac and Linux.
Google Sheets
Upload the .ods to Google Drive — right-click → Open with Google Sheets. Converts automatically with all data intact.
Microsoft Excel
Excel 2010+ opens .ods files natively via File → Open. Some advanced formatting may not transfer.
OpenOffice Calc
ODS is OpenOffice's native format. Opens directly without any conversion or import dialog.
Numbers (Mac/iOS)
Apple Numbers opens .ods files on Mac and iOS via File → Open. Standard ODS content imports correctly.
OnlyOffice
Full ODS support in OnlyOffice Desktop, cloud and mobile — part of the OpenDocument standard it implements.
How CSV to ODS conversion works
SheetJS generates a real ODS binary in your browser.
1
Upload your CSV
Drop your .csv file. CSVShift parses it with the RFC 4180 parser and shows a live preview table. The sheet name is pre-filled from your filename.
2
SheetJS builds the ODS
SheetJS creates an in-memory workbook with auto-fitted column widths and optional type detection, then serialises it using bookType: 'ods' to produce a binary Uint8Array.
3
Download and open in LibreOffice
The ODS binary is wrapped in a Blob and downloaded directly. Open in LibreOffice Calc, Google Sheets or any OpenDocument-compatible application.
When do you need CSV to ODS?
Government and public sector
Many European government bodies mandate ODF for document exchange. Converting data exports from CSV to ODS ensures compliance when submitting data to public sector systems.
Sharing with LibreOffice users
Colleagues using LibreOffice receive ODS files that open natively without any import dialog. A CSV opens with the Text Import Wizard; an ODS opens immediately with correct column types.
Open-source workflows
Teams committed to open-source software prefer ODS over XLSX for spreadsheet data. ODS avoids Microsoft Office format dependencies and works across all major operating systems.
Google Drive integration
ODS files uploaded to Google Drive are automatically detected as spreadsheets and opened with Google Sheets — a convenient intermediate format between LibreOffice desktop and Google Sheets cloud users.
CSV to ODS in Python
Python — pandas
import pandas as pd
df = pd.read_csv('data.csv')
# Requires: pip install odfpy
df.to_excel('output.ods', engine='odf', index=False)
Requires: pip install pandas odfpy. The odf engine writes proper OpenDocument Spreadsheet format compatible with LibreOffice and Google Sheets.

How do I convert CSV to ODS?

ODS (OpenDocument Spreadsheet) is the ISO-standardised open-standard spreadsheet format. It is the native format of LibreOffice Calc and OpenOffice Calc, supported by Google Sheets, Microsoft Excel 2010+, Apple Numbers and any application that implements the OpenDocument Format standard.
Is there a difference between ODS and XLSX?
Both store data types, formulas and formatting. XLSX is Microsoft's format — best for Excel. ODS is the open-standard format — best for LibreOffice users and open-source workflows. Use ODS when your recipient uses LibreOffice or when open-standard compliance is required.
Is my data safe when converting CSV to ODS online?
Yes. SheetJS generates the ODS file entirely in your browser. Your CSV is never uploaded to any server.
