Export JSON to CSV for Spreadsheets and APIs
Convert JSON arrays from API responses into CSV format for Excel, Google Sheets, or data pipelines. Free, instant, browser-based.
The Problem
Your API returns JSON but your stakeholders need data in Excel or Google Sheets. You could write a Python script every time — or convert it in 10 seconds online.
Why This Matters
JSON-to-CSV conversion is one of the most common data transformation tasks in web development. API responses, database exports, and webhook payloads all use JSON. Analysts, product managers, and data teams need CSV. This bridge saves developers from writing one-off conversion scripts repeatedly.
Step-by-Step Instructions
Paste your JSON array
Copy the JSON array from your API response, database query result, or webhook payload. The tool handles arrays of objects (most common API format).
Review the preview
The converter automatically detects all keys from your objects and uses them as CSV column headers. Nested objects are flattened.
Download or copy the CSV
Click Download to get a .csv file, or Copy to paste the data directly into Excel or Google Sheets.

Frequently Asked Questions
Does this handle nested JSON objects?
The converter flattens one level of nesting. For deeply nested JSON, format and flatten it first using the JSON Formatter tool.
What if my JSON array has inconsistent keys?
The tool uses the union of all keys found across all objects. Missing values become empty cells in the CSV.
Can I convert JSON to CSV in Python instead?
Yes: import csv, json; data = json.load(f); writer = csv.DictWriter(out, fieldnames=data[0].keys()); writer.writerows(data). Use this tool for quick one-off conversions.
