Frequently Asked Questions

Our converter works best with:

Key-value pairs (one per line)
Simple lists (with bullets or dashes)
CSV-like data (comma separated values)
Plain text with clear structure

For complex structures, you may need to manually adjust the JSON after conversion.

When enabled, the tool will:

Convert numeric strings to actual numbers (e.g., “30” becomes 30)
Convert “true”/”false” strings to booleans
Leave other values as strings

This helps create more semantically correct JSON for your applications.

Yes! Use indentation to indicate nesting:

user:
  name: John Doe
  address:
    street: 123 Main St
    city: Anytown
    zip: 12345

The converter will create proper nested JSON objects from this structure.

There’s no hard limit, but very large texts (10,000+ lines) may slow down your browser since all processing happens client-side. For extremely large datasets, consider breaking them into smaller chunks.
