JSON ↔ Markdown table

Client

Turn a uniform array of objects into a pipe table for docs and issues, or parse a simple GitHub-flavored table back into JSON. Pipes inside cell values are escaped as | on export.

Convert a JSON array of objects to a GitHub-flavored pipe table (and back)—handy for READMEs, issues, and docs that mix prose with small datasets.

Format

Tables need a header row, a separator row with dashes, and one row per object. Column names come from the union of keys; pipe characters inside values are escaped as `|` in the Markdown text.

JSON ↔ Markdown table

?

GitHub-style pipe tables: header, |---| separator, then rows. JSON must be a non-empty array of objects; column union matches the HTML table tool pattern.

Pipe characters inside cell values are written as | on export.

Common use cases

  • Drop a small API sample into a README without hand-aligning pipes.
  • Import a table someone pasted in an issue into JSON for further tooling.

Common mistakes to avoid

  • Tables with merged cells or HTML

    Only classic pipe tables are supported—no colspan, nested Markdown, or block markup inside cells.
