How do I convert JSON to Excel online?
Open www.jsontoexcel.in, drop your .json, .jsonl, or .ndjson file (up to 15 MB), preview the table, and click Download Excel. The file opens in Microsoft Excel, Google Sheets, or LibreOffice with readable column headers.
Is the JSON to Excel converter free?
Yes, it is completely free with no signup and no payment. Convert and download as many JSON, NDJSON, and API exports as you like - up to 5 files per batch, each up to 15 MB.
Does it support nested JSON and API responses?
Yes. By default, nested objects are flattened into columns (for example user.address.city) using Separate columns mode - or you can switch to JSON in one cell to keep each nested object as JSON text instead. Common API wrappers such as data, results, items, and records are detected automatically, and when a file has two or more top-level lists of objects, each list becomes its own Excel sheet.
Can I convert NDJSON or JSON Lines (.jsonl) to Excel?
Yes. Upload .jsonl or .ndjson files with one JSON object per line. The tool parses each line and builds a single spreadsheet, ideal for logs and streaming exports.
What is the maximum file size?
Each file can be up to 15 MB, and you can convert up to five files in one batch - free, with no limit on how many batches you run.
Is my JSON data stored on your servers?
Conversion runs entirely in your browser, so your JSON never leaves your device and we never keep a copy of it. Lightweight session metadata (such as anonymous usage counts) may be stored to operate the service - see our Privacy Policy.
Will large numbers and IDs stay accurate in Excel?
Long numeric IDs should be strings in your JSON (quoted) so they are not rounded. The converter uses a bigint-safe parser and preserves string IDs in Excel cells.
Does it work with Postman or webhook JSON exports?
Yes. Paste or export JSON from Postman, Stripe, Shopify, or other webhooks. JSON embedded inside string fields can expand into columns when you use Separate columns mode.
