How to convert HTML to JSON
Add your HTML web pages
Drop HTML (HTM) 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 HTML to JSON converter is part of this page and runs inside your browser. Your web pages 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.
HTML to JSON: what to expect
An HTML file depends on a browser and often on separate image and style files. JSON is what APIs and most programming languages read natively. HTML is at home in web pages and emails; JSON is the usual choice for APIs and data exchanged between programs.

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 web pages uploaded anywhere?
No. The HTML 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 HTML to JSON?
The content is carried over as faithfully as JSON allows; features that JSON does not have are left out.
Can I convert several HTML 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 HTML 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 HTML file, press Convert and save the JSON. There is nothing to install.
Is there a file size limit?
Yes. Data files up to 300 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.
