How to convert HTML to JSON

  1. Add your HTML files

    Drag one or more HTML files onto the dashed area, or tap it to pick them from your device.

  2. Choose JSON and the options

    JSON is already selected; the options hold the settings that matter for this conversion.

  3. Convert and download

    Press “Convert to JSON”. When it’s done, download the files one by one or all together in a ZIP archive.

Good to know. The <table> elements of the page are read; the rest of the content is ignored.

Questions about HTML and JSON

Are my HTML files uploaded to a server?

No. The conversion from HTML to JSON happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.

How many files can I convert at once?

Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.

Does it work on iPhone and Android?

Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.

Do I need an internet connection?

Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
