Frequently Asked Questions

How do I fix "Unexpected token" errors?

This usually means there's a syntax error in your JSON. Common causes include missing commas, unmatched brackets, or unescaped quotes. Use our validator to pinpoint the exact location of the error.

Can I process multiple JSON files at once?

Currently, our tools process one file at a time. For batch processing, you can use our tools programmatically or contact us about enterprise solutions.

What's the maximum file size I can process?

Our tools can handle files up to 10MB. For larger files, consider breaking them into smaller chunks or using our API endpoints with pagination.

How do I open JSON files in Excel?

Use our JSON to Excel converter, or convert to CSV first. Excel can import JSON through Data → Get Data → From File → From JSON. See our detailed guide on the converter page.
