How the conversion works

Paste your HTML Table on the left and press Convert. The tool first parses the HTML Table (reading the first

element and using its th cells as column names) into an internal table of rows and columns, then writes it out as JSON (pretty-printed with 2-space indentation). If the input cannot be parsed you get a plain-English error instead of a broken file.

Where this comes in handy

People reach for this converter when reusing tables copied from web pages or documentation and JSON is needed for APIs and JavaScript apps. Because everything runs locally in your browser, it is also handy for quick one-off migrations without installing database tools or writing throwaway scripts.

HTML Table to JSON FAQs

Which table is converted if my paste has several?
The first <table> element in your paste is used. To convert a different one, paste only that table's HTML source.
What happens to merged cells with colspan or rowspan?
Merged cells are read as the plain text of each td or th in row order. The spanned layout is not reconstructed, so check that the column count looks right.
Are numbers kept as numbers in the JSON?
Yes. Numeric cells are emitted as JSON numbers, booleans stay booleans, and empty cells become null.
Can I feed the output straight to an API?
Yes. The output is a plain JSON array of objects, which most REST APIs and JavaScript apps accept directly.
Is my data uploaded anywhere?
No. Parsing and conversion run entirely in your browser with JavaScript. Your data never leaves your device.
