Paste a table or use Example.

An HTML table sitting on a page, scraped from a Wikipedia article or copied out of a report, is structured data trapped inside markup, and getting it into a form a script can actually loop over means parsing out the header row, matching each cell to its column, and assembling the result as an array of objects, tedious to do by hand for anything beyond a handful of rows. This tool converts HTML tables into JSON arrays with automatic header detection, extracting existing table markup into structured data rather than building a table from nothing.

Quick answers for HTML Table to JSON

How does it detect table headers?
It first looks for <th> cells in the table; if none exist, it falls back to using the text of the first row's <td> cells as the header names.
What does the JSON look like when headers are found?
An object with a headers array and a rows array, where each row is keyed by the matching header name instead of a plain positional array.
What if a table has no headers at all?
Each cell gets a generic key like col0 and col1 based on its position, and the output becomes a plain array of those row objects.
