A little guidance.
Convert a JSON array of objects into CSV using the union of their keys as columns. Nested arrays and objects are serialized as JSON inside cells. Formula-like cells can be neutralized for safer spreadsheet opening.
How it works
- Enter your values, or use the example to get started.
- Select “Convert to CSV” to process your input in your browser.
- Review the result, then copy or download it when available.
Good to know.
What happens to missing or nested values?
Missing and null values become empty cells. Nested values become JSON text. Formula neutralization changes formula-like text by adding an apostrophe; disable it only when you need exact raw values.
Is my input sent to a server?
No. This tool runs in your browser. KILIZU does not upload or store the values or files you enter here.
