Convert API JSON to Excel CSV
Take a real API response and turn it into a CSV that Excel can open cleanly.
🔒 The tool runs entirely in your browser — your data never leaves your device. How we verify this.
API responses are built for software, not spreadsheets
Most API responses include nested objects, links, metadata, and arrays. Excel wants a flat table. This page shows how to turn the useful parts of an API response into columns while leaving out the fields that only add noise. Preview first, then export a CSV with the columns your spreadsheet actually needs.
How it works
- Paste an API JSON response or load the sample.
- Flatten nested objects and choose the columns to keep.
- Export the result as CSV and open it in Excel or Sheets.
FAQ
Will this remove unnecessary API fields automatically?
No. It shows the detected columns and lets you choose what to keep. That is safer than guessing, especially with API data that may contain IDs, URLs, metadata, or private fields.
