About the ODS to JSON Converter
Need to turn a ODS file into JSON? This free converter changes ODS spreadsheets into JSON in a few seconds, right in your browser. People usually convert because many tools and portals only accept Excel or CSV files, while JSON gives you structured JSON. JSON files open in every programming language, VS Code, Postman, browsers and databases.
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 spreadsheets 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: every sheet in the workbook is converted; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact; the first row is used as column names, which you can switch off.
How to use the ODS to JSON Converter
- Click "Choose files" or drag your ODS spreadsheets onto the box. You can add several at once.
- Choose whether the first row holds column names and whether to convert all sheets or only the first.
- Press "Convert to JSON". The conversion runs on your device and shows its progress.
- Download each JSON file, or use "Download all (ZIP)" when you converted several.
- Open the result in every programming language or VS Code to check it; your original ODS is never changed.
Tips & benchmarks
- The JSON is pretty-printed with two-space indentation and numbers and booleans keep their types.
- 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 JSON to a website or government portal.
Frequently asked questions
How do I convert ODS to JSON?
Click "Choose files", select your ODS spreadsheets, adjust the options if you want, and press "Convert to JSON". The JSON downloads immediately; with several files you can download everything as one ZIP.
Is this ODS to JSON 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 spreadsheets 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 ODS files at once?
Yes. Add as many ODS 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 ODS and JSON?
ODS (OpenDocument Spreadsheet) is a open-standard spreadsheet best suited to LibreOffice Calc users and open, vendor-neutral data archiving. JSON (JavaScript Object Notation) is a structured data (text) best suited to APIs, web and mobile apps, configuration and MongoDB or Firebase data.
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 ODS to JSON in Excel?
In Excel choose File → Save As and pick the format. This converter does it without Excel installed.

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.
What is a JSON file?
JSON is the data format of the modern web: almost every API, app configuration and NoSQL database speaks it. It represents objects, arrays, numbers and text in a compact, human-readable way.
