JSON to CSV Converter
Convert an array of flat JSON objects to a table.
How to use the json to csv converter
- Choose a supported file or enter the data requested by the tool.
- Choose the available options and run the tool.
- Review the result and download the output in a supported format.
Worked example
[{"Product":"Mug","Price":120}] becomes a table with Product and Price headings and one row.
Understanding the result
Use an array of flat objects. Keys become column headings; missing values become blanks. Nested objects and arrays are rejected rather than silently flattened.
Frequently asked questions
Are nested JSON objects supported?
No. Prepare flat objects first. This prevents ambiguous column names and unexpected loss of nested values.
Is this JSON to CSV converter free to use?
Yes. This version of AllgoTool is free to use and does not require an account. The tool’s limits are explained above.
Supported inputs and limitations
CSV and .xlsx supported. First worksheet only; up to 1,000 data rows and 50 columns. Files stay in your browser. Exports contain text values; styling and formulas are not preserved.
