Frequently asked questions
What JSON structure produces the best table?
An array of flat objects with consistent keys — each object becomes a row and the union of all keys becomes the header columns.
Is the output ready to paste into a web page?
Yes — it's a complete, indented <table> element with a <thead> and <tbody> that you can paste directly into HTML.
How are special characters handled?
Characters like <, > and & in your values are escaped so the generated table renders correctly and isn't broken by embedded markup.
