Frequently Asked Questions

What input format is required?▾
The input must be a JSON array of objects, where all objects share the same keys. For example: [{"col1":"val1","col2":"val2"},{"col1":"val3","col2":"val4"}].
What if my JSON has nested objects?▾
Nested objects are stringified as-is. For best results, flatten your JSON before converting — nested objects will appear as [object Object] in the table.
Where can I use Markdown tables?▾
GitHub README files, GitLab, Bitbucket, Notion, Obsidian, Discord and most Markdown editors support pipe-style tables.
