Frequently Asked Questions About Free Online JSON to Table Converter

Can it fix JSON with trailing commas or comments?

Yes. The repair step removes trailing commas, comments and a byte-order mark, turns single-quoted strings into double-quoted ones and quotes bare member names, then re-reads the document. Values it cannot infer, such as a Python True or a missing closing brace, still need a manual edit.

Why do large numbers change when I format JSON?

JavaScript numbers are IEEE-754 doubles, so most parsers rewrite an integer above 2^53 and lose its tail digits. This page keeps those long literals exactly as you typed them, but a parser elsewhere in your stack will not, so keep such ids as strings in the source document.

What happens to missing keys?

Cells with no value stay empty, which is how you spot inconsistent records.

Can I copy the table into Excel?

Copy the CSV output where offered, then paste; the grid itself is for reading and checking.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It uses objects {}, arrays [], strings, numbers, booleans, and null.

Why format JSON?

API responses and config files are often minified. The JSON to Table Converter expands them with indentation so you can spot nested keys, validate structure, and debug faster.
