About the CSV to ODS Converter
This CSV to ODS converter turns data files from CSV into ODS without installing software or uploading anything. It solves a common problem: CSV has no formatting, no sheets and no data types. Converting to ODS gives you a LibreOffice Calc spreadsheet, ideal for LibreOffice Calc users and open, vendor-neutral data archiving.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your data files are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: the delimiter and text encoding are detected automatically; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact.
How to use the CSV to ODS Converter
- Click "Choose files" or drag your CSV data files onto the box. You can add several at once.
- Choose whether to convert all sheets or only the first one.
- Press "Convert to ODS". The conversion runs on your device and shows its progress.
- Download each ODS file, or use "Download all (ZIP)" when you converted several.
- Open the result in LibreOffice Calc or OpenOffice to check it; your original CSV is never changed.
Tips & benchmarks
- All sheets are preserved and the file opens directly in LibreOffice Calc and Excel.
- Merged cells are unmerged and their value is kept in the first cell, which keeps the data easy to filter and import.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the ODS to a website or government portal.
Frequently asked questions
How do I convert CSV to ODS?
Click "Choose files", select your CSV data files, adjust the options if you want, and press "Convert to ODS". The ODS downloads immediately; with several files you can download everything as one ZIP.
Is this CSV to ODS converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your data files never leave your phone or computer and nothing is stored on News Appite's servers.
Are formulas, formatting and all sheets kept?
Every sheet is converted (or only the first, if you choose). Formulas are exported as their current values, and cell colours and fonts are not carried over because formats such as CSV, JSON and SQL cannot store them.
Can I convert several CSV files at once?
Yes. Add as many CSV files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between CSV and ODS?
CSV (Comma-Separated Values) is a plain-text table best suited to importing data into databases, CRMs, Tally, mailing tools and Python or R. ODS (OpenDocument Spreadsheet) is a open-standard spreadsheet best suited to LibreOffice Calc users and open, vendor-neutral data archiving.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert CSV to ODS in Excel?
Open the file in Excel via Data → From Text/CSV (choose UTF-8 for Hindi or ₹), then use File → Save As. This converter does it instantly and keeps leading zeros such as PIN codes.
How do I convert CSV to ODS in Python?
With pandas: df = pd.read_csv('input.csv'), then df.to_excel('output.ods', engine='odf', index=False). If you just need the file, this converter does it in the browser without writing any code.

What is a CSV file?
CSV stores a single table as plain text, one row per line with values separated by commas. Every spreadsheet, database, CRM and programming language can import it, which makes it the universal format for moving data.
What is a ODS file?
ODS is the OpenDocument spreadsheet format used by LibreOffice Calc. Like XLSX it supports multiple sheets and formulas, but it is an open ISO standard favoured by open-source users and many public bodies.
