What is a JSON to CSV converter?
It takes an array of JSON objects and turns it into CSV, the simple text format used by spreadsheets. Each object becomes a row, and every unique key becomes a column header.
This is the quickest way to move API data or configuration JSON into Excel, Google Sheets or a database import. One click and you have a file your whole team can work with.
How to use this tool
Paste an array of JSON objects.
Click Convert to CSV.
Review the table preview to confirm the columns look right.
Download the .csv file or copy the raw text.
What the preview shows
After conversion you see the first rows as a table. This lets you check the headers and spot data problems before you commit to the file. The raw CSV text is also available if you want to paste it somewhere directly.
A quick note on nested data
CSV is a flat format, so it cannot hold nested objects. This tool keeps things simple: any nested object or array is stored as readable JSON text inside its cell, while flat values stay clean and usable.
Frequently Asked Questions
The tool reads an array of JSON objects, collects every unique key as a column header, then writes each object as a row. Nested objects and arrays are stored as JSON text inside a cell.
An array of flat objects works best, like [{"name":"A","price":5},{"name":"B","price":8}]. Objects with different keys still convert, the tool simply includes every key it finds.
Yes. Download the .csv file and open it in any spreadsheet app. The first row becomes the header and each object becomes a row.
Nested objects and arrays are turned into JSON text inside the cell. Flat values like strings and numbers are written normally so they stay usable in formulas.
No. The conversion happens entirely in your browser. Nothing is uploaded, which makes this safe for customer or financial data.
If a value contains commas or quotes it is wrapped in quotes by the converter, which some spreadsheet apps treat as text. Removing those characters before converting avoids the issue.
