How to use this tool
Paste an array of 1 to 5,000 objects. Columns follow the first appearance of each key; missing and null values become empty cells, while nested values become JSON text. Choose comma, semicolon or tab. Formula-like strings receive an apostrophe by default. JavaScript number precision applies: quote large identifiers before converting.
Try these values
[{"name":"Ada","score":9}] becomes a header row name,score followed by Ada,9. A comma inside a value causes that cell to be quoted.

Does my input leave this page?
The tool processes its input in your browser. It does not send the text to our server for calculation. If advertising is enabled, third-party ad scripts also run on the page; use a trusted offline tool for secrets.
Can I use the result in my project?
Yes. Check the example and limitations first, and test the output with the system that will consume it.
