How it works

Three steps, no account

1

Paste or drop your JSON

An array of objects works best. You can also upload a .json file directly.

2

Review the table

Transpose it, delete blank rows, or remove duplicates before you generate output.

3

Pick a format and generate

Choose from 28 output formats, then copy the result or download it as a file.

FAQ

Common questions

Is my data uploaded anywhere?
No. Parsing, editing, and generating output all run in your browser using JavaScript — the JSON you paste or upload never touches a server.
How large a file can I convert?
There's no server-side limit because there's no server involved — your browser's own memory is the ceiling.
What happens to nested objects and arrays?
Each top-level key becomes a column. A nested object or array is written to its cell as its default text representation rather than split into separate columns — flatten your JSON to one level first if you need each nested field broken out on its own.
Can I edit the data before converting?
Yes — the table below the input lets you transpose rows and columns, delete blank rows, or remove duplicate rows before you generate the final output.
