About the ODS to CSV conversion
A practical look at what happens during this conversion, what to expect from the output, and the trade-offs involved.
ODS is the OpenDocument Spreadsheet format used by LibreOffice Calc and other open-source office tools. CSV is the universal flat-text format every data tool understands. Converting ODS to CSV extracts the cell values from the spreadsheet (typically just the active sheet's used range) and writes them out as comma-separated rows.
Multi-sheet ODS files are handled by either selecting a specific sheet or producing one CSV per sheet (delivered as a ZIP). MegaConvert defaults to converting the first sheet by default; specify a sheet name explicitly to convert a different one. For workbooks with many small sheets, the multi-CSV-as-ZIP option is usually most useful.
Cell values are output as their displayed string form by default — formulas are evaluated and the result written, currency formatting becomes plain numbers, dates become ISO-formatted strings (YYYY-MM-DD). For raw cell values without formula evaluation, request the 'raw' export mode. Empty cells become empty CSV fields; explicitly-zero cells become '0'.
Character encoding handling: the CSV is written as UTF-8 with optional BOM. UTF-8 is the modern standard and handles all characters correctly. For cells with content that includes commas, quotes, or newlines, those values are properly escaped according to RFC 4180 (wrapped in double quotes, internal quotes doubled).
Watch out
Date formatting depends on the spreadsheet's locale
Dates in the source ODS may be stored in any locale-specific format (DD/MM/YYYY in Europe, MM/DD/YYYY in the US). The CSV output uses ISO format (YYYY-MM-DD) by default for unambiguous machine parsing. If you need a different format for human reading, post-process the CSV in Excel or your data tool of choice.
Pro tip
Save as UTF-8 with BOM for Excel compatibility
If the CSV will be opened in Excel and contains accented or non-Latin characters, request the 'UTF-8 with BOM' encoding option. Excel needs the BOM to detect UTF-8 correctly; without it, accented characters display as garbled. Other tools (Python pandas, R, BigQuery) handle UTF-8 correctly with or without BOM.
When not to convert
When you should keep the ODS
If your data uses formulas, formatting, multiple sheets, or charts, ODS preserves all of that and CSV doesn't. Convert to CSV only when the destination explicitly needs a flat tabular format. For human-edited spreadsheets, ODS or XLSX is usually the right format to keep.
When to convert ODS to CSV
Use this conversion when your destination needs CSV and you have a ODS source. Keep the original so you can compare the result or try another supported format.
Text, layout, fonts, images, tables and metadata can change between document formats. Check all pages before relying on the result. OCR and exact layout preservation are not promised.

How to Convert ODS to CSV
Follow these simple steps to convert your file in seconds.
Choose a ODS file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.
Convert to CSV
Text, layout, fonts, images, tables and metadata can change between document formats. Check all pages before relying on the result. OCR and exact layout preservation are not promised.
Download and check the result
Use Download after conversion completes. Open the result and check its content, quality and formatting before sharing it. Download links expire one hour after upload finishes. Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting ODS to CSV
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
OpenDocument Spreadsheet has a known limitation: some Excel formulas and features may not convert perfectly. CSV File addresses this with a key advantage: universal compatibility with virtually every data application and programming language. Converting from ODS to CSV is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
OpenDocument Spreadsheet is most commonly used for spreadsheet creation in libreoffice and openoffice, while CSV File is the standard for data export and import between databases and applications. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where ODS is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the CSV output
CSV File has its own limitation worth understanding before you commit: no support for data types, formatting, formulas, or multiple sheets. After the conversion completes, open the CSV file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Understand the editing vs. viewing trade-off
Some document formats are designed for editing (DOCX, ODT), while others are intended for final distribution (PDF). Converting to PDF locks in your formatting and makes it difficult to edit the content later. If you plan to revise the document further, keep an editable source copy before converting.

Source Format
OpenDocument Spreadsheet
application/vnd.oasis.opendocument.spreadsheetODS (OpenDocument Spreadsheet) is an open-standard spreadsheet format defined by the OASIS OpenDocument specification. It is the native format for LibreOffice Calc and Apache OpenOffice Calc, storing data, formulas, charts, and formatting in XML within a ZIP archive. ODS provides a vendor-neutral alternative to proprietary Excel formats.
Advantages
- Open standard not controlled by any single software vendor
- Free to use with LibreOffice, OpenOffice, and Google Sheets
- Well-defined XML schema for reliable programmatic access
Limitations
- Some Excel formulas and features may not convert perfectly
- Less widely used in corporate environments that standardize on Excel
- Macro compatibility with Excel VBA is limited
Common Uses
- Spreadsheet creation in LibreOffice and OpenOffice
- Government and public sector data in jurisdictions mandating open formats
- Cross-platform spreadsheet sharing without Excel dependency
Target Format
CSV File
text/csvCSV (Comma-Separated Values) is a plain-text tabular data format where each line represents a row and values within a row are separated by commas. It is the most universal format for exchanging structured data between different applications, databases, and programming languages. CSV files contain only raw data with no formatting, formulas, or multiple sheets.
Advantages
- Universal compatibility with virtually every data application and programming language
- Human-readable plain text that can be opened in any text editor
- Extremely lightweight with no overhead beyond the data itself
Limitations
- No support for data types, formatting, formulas, or multiple sheets
- Inconsistent handling of commas within values across different parsers
- No standardized encoding, leading to potential character set issues
Common Uses
- Data export and import between databases and applications
- Data science and machine learning dataset distribution
- Bulk data exchange and ETL (Extract, Transform, Load) pipelines
