How to Convert JSON to CSV
Step-by-step guide to transforming a JSON array into a comma-separated values file using the DevHexLab JSON to CSV tool.
Tool Used
JSON to CSV
Open the JSON to CSV tool
Navigate to /tools/json/json-to-csv. The left panel accepts JSON input and the right panel shows the CSV output.
Paste a JSON array
The tool expects a JSON array of objects where each object becomes one row and each key becomes a column header. Paste your array into the input field. Nested objects are flattened automatically.
Click Convert
Press the Convert button. The tool reads every key from the first object to create the header row, then fills in the values for every subsequent object.
Review the CSV preview
Check the output to make sure columns match your expectations. If a value contains a comma or a newline, the tool wraps it in double quotes automatically so the CSV stays valid.
Download or copy
Click Download CSV to save the file directly to your computer, or click Copy to grab the raw text and paste it into a spreadsheet application like Excel or Google Sheets.
All done!
You are ready to use JSON to CSV like a pro.
