HTML Table Generator

Code

Generate HTML and Markdown tables from CSV, TSV, or pipe-delimited data

Paste CSV or TSV copied out of a spreadsheet and get back a ready-to-use HTML `<table>` or a GitHub-flavored Markdown table, with the delimiter auto-detected or switchable if your data uses pipes or something else entirely. It's a fast way to turn a quick data dump into something that renders properly in a README or a web page without hand-writing table markup row by row. Parsing splits on the delimiter directly, so a field that itself contains a comma or quote inside a quoted value can throw off column alignment; simple, unquoted CSV converts cleanly, but anything with embedded delimiters is worth a quick check of the output before using it. Conversion runs entirely client-side.

How to use HTML Table Generator

  • 1.Paste CSV data copied from a spreadsheet to instantly generate a semantic HTML `<table>` you can drop into a page.
  • 2.Paste tab-separated (TSV) data exported from Excel to get clean Markdown table syntax for a README or GitHub issue.
  • 3.Switch delimiters to pipe-delimited when working with data copied from a database query tool or log file that isn't comma-separated.

Frequently asked questions

Does it auto-detect the delimiter?
It makes a best guess based on the pasted data, but you can manually select CSV, TSV, or pipe-delimited if the detection picks the wrong one.
Does this handle quoted fields with commas inside them?
No, parsing just splits each line on the delimiter directly — it doesn't recognize double-quoted fields, so a value like "Smith, John" will be split into two columns instead of staying together. Strip or replace embedded delimiters in quoted fields before pasting, or use a delimiter that doesn't appear in your data.
Is my data uploaded anywhere?
No, the conversion happens entirely client-side in your browser.
Can I generate a table with a header row automatically?
Yes, there's an option to treat the first row as the header, which produces `<th>` cells in HTML or the `---` separator row in Markdown.
