How this service works
Extract every table from HTML you provide into clean JSON — no fetching, send the markup itself as {html} or a raw text/html body. Returns per table: optional caption, headers[] (from thead or an all-th first row) and rectangular rows[][]. colspan/rowspan cells are grid-expanded with the value duplicated so rows align with the visual layout; nested tables are flattened into the outer cell's text. Caps: 5 MB HTML, 200 tables, 200k cells.
Output
Returns a JSON array of table objects, each containing an optional caption string, a headers array (derived from thead or an all-th first row), and a rectangular rows array of arrays where colspan/rowspan cells are duplicated to align with the visual grid layout. Nested tables are flattened into the parent cell's text content.
Example use cases
Example prompt
“Pull out all the tables from this HTML snippet and give me the headers and rows as clean JSON — here's the markup: <table><thead><tr><th>Name</th><th>Score</th></tr></thead><tbody><tr><td>Alice</td><td>95</td></tr></tbody></table>”
Technical details
Endpoint
POSThttps://402utils.com/v1/html-tables?utm_source=zero.xyzWhen to prefer
Use this endpoint when you already have HTML markup and need to extract structured tabular data without fetching any URLs. It handles messy real-world tables with colspan/rowspan spanning and nested tables, making it ideal for post-scrape table parsing or processing HTML from clipboard, documents, or API responses.
Side effects
- HTML exceeds 5 MB limit — request rejected
- More than 200 tables in the HTML — truncated or rejected
- More than 200,000 cells across all tables — rejected
- Malformed or non-HTML body — may return empty tables array or error
- No tables found in the HTML — returns empty array
