Frequently Asked Questions

How do I convert JSON to Excel?

Paste your JSON data into the editor above, or drag and drop a .json file. Click "Export to Excel" to download a formatted .xlsx file instantly. No signup or upload required.

Can I convert JSON to XLSX online for free?

Yes. JsonExport is 100% free with no limits on file size or conversions. Your data is processed entirely in your browser — nothing is uploaded to any server.

How do I open a JSON file in Excel?

You cannot open a JSON file directly in Excel without converting it first. Use this tool to convert your JSON to an .xlsx file, then open it in Excel. Alternatively, Excel's Power Query can import JSON but struggles with nested data.

Does this handle nested JSON and arrays?

Yes. Our Smart Flattener automatically detects nested objects and arrays, converting them into separate columns using dot notation (e.g., "address.city"). Arrays are expanded into individual rows.

What is the maximum JSON file size supported?

JsonExport handles files up to 100MB+ directly in your browser. For very large files, processing happens in Web Workers to prevent UI freezing.

Why does my JSON show [object Object] in Excel?

This happens when Excel encounters nested JSON objects it cannot display. JsonExport solves this by flattening nested structures into readable columns before generating the Excel file.

Is my data secure when converting JSON to Excel?

Yes. JsonExport processes everything 100% client-side in your browser. Your JSON data is never sent to any server. You can even disconnect from the internet after loading the page.

Can I convert JSON to CSV instead of Excel?

Yes. JsonExport supports export to Excel (.xlsx), CSV, and HTML table formats. Use the format selector above the export button to choose your preferred format.

How do I convert a large JSON file to Excel without crashing?

Most online converters crash on large files because they upload data to servers. JsonExport processes files locally using Web Workers, handling 50MB+ files smoothly without memory errors.

Can I convert JSON from APIs like Stripe, Salesforce, or HubSpot?

Absolutely. JsonExport is designed to handle real-world API responses with deeply nested metadata. We have dedicated converter pages for Stripe, Salesforce, HubSpot, Slack, and 20+ other platforms.
