JSON to Markdown Table FAQ
What JSON format is needed?
An array of objects: [{"col1":"val1","col2":"val2"},...]. Each object becomes a table row, keys become column headers.
How does column alignment work?
The tool calculates the maximum width of each column and pads values with spaces for clean alignment in the raw Markdown.
Can I use this for GitHub README files?
Yes, the generated Markdown is GitHub Flavored Markdown compatible and renders correctly in README files, issues, and PRs.
What happens with missing fields?
If some objects lack certain fields, those cells display the null placeholder (default "N/A").
How are nested objects handled?
Nested objects and arrays are JSON-stringified into the cell. For complex data, consider flattening first.
