0 / 30,000 characters. No upload, storage, or account required.
Table header extraction workflows
Use table header extraction when table columns need a quick pasted-markup inventory before CSV conversion, QA notes, or documentation cleanup.
Map table columns
Pair this with Extract Table Rows when you need both column labels and row values from the same pasted table.
Inspect cell text
Use Extract Table Cells when the table body values need a simple one-cell-per-line inventory.
Clean the final list
Send copied headers to Remove Duplicate Lines, Sort Lines, or CSV to List.
What this tool does
Extract Table Headers finds th text in pasted HTML table snippets, strips nested markup, removes duplicates, shows source lines, and runs locally in your browser.
Common use cases
Extract header cell text from pasted HTML tables, documentation snippets, CMS output, and copied source before column mapping, spreadsheet recovery, QA review, or migration documentation.
Use Extract Table Headers when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste HTML table markup, documentation snippets, CMS output, or copied source that contains th header cells.
- Choose whether duplicate header labels should be removed and whether output should be normalized for comparison.
- Review the extracted column names with source lines, then copy the clean list for spreadsheet mapping, migration docs, or tests.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Table header extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, execute, or log the HTML table text you paste.
