How to Convert JSON to Excel Online
A step-by-step guide to turning JSON arrays into CSV and XLSX tables in your browser.
When you need this
API responses, log exports, and config data often arrive as JSON arrays. A table makes them easier to scan, compare, and share.
Steps
- Paste your JSON, upload a .json file, or load an example.
- Click Convert. The tool extracts every array and flattens nested objects.
- Switch tabs to inspect each table.
- Download the current table as CSV/XLSX, or all tables as one XLSX.
Common JSON input types
Top-level arrays, objects wrapping arrays (data.orders), and fragments missing outer braces that are auto-repaired.
Handling multiple arrays
Each detected array becomes a tab named by its path, e.g. data.orders and data.refunds. Download all to get one sheet per array.
Q&A
Is my data safe?
Yes — everything runs in your browser; nothing is uploaded.
What about nested arrays?
They stay as JSON strings inside a cell and are not expanded.
