How to convert ODS to JSON
Add your ODS spreadsheets
Drop ODS files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
JSON is already chosen
Press Convert. There is nothing else to set. The work happens in this tab.
Download
Save the JSON, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The ODS to JSON converter is part of this page and runs inside your browser. Your spreadsheets are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
ODS to JSON: what to expect
ODS is not what most colleagues or import tools expect. JSON is what APIs and most programming languages read natively. ODS is at home in spreadsheets in open-source office suites; JSON is the usual choice for APIs and data exchanged between programs.
The first row is read as column names, and every row after it becomes one object, keyed by those names. A header such as address.city is turned back into a nested address with a city. A workbook with a single sheet becomes a plain list; one with several sheets becomes an object keyed by sheet name. Formulas come across as the values they last calculated, and formatting such as colours and column widths is not carried over.
ODS vs JSON
JSON
JSON data
JSON represents data as nested objects and lists in plain text. It is the default language of web APIs. Unlike a spreadsheet it can be nested to any depth, which is also why turning it into rows and columns takes a decision about how to flatten it.

Questions
Are my spreadsheets uploaded anywhere?
No. The ODS to JSON conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Is anything lost when converting ODS to JSON?
The values are kept. Anything JSON has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Can I convert several ODS files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert ODS to JSON on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the ODS file, press Convert and save the JSON. There is nothing to install.
Is there a file size limit?
Yes. Spreadsheet files up to 150 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
