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.
Currently, our tools process one file at a time. For batch processing, you can use our tools programmatically or contact us about enterprise solutions.
Our tools can handle files up to 10MB. For larger files, consider breaking them into smaller chunks or using our API endpoints with pagination.
