Troubleshooting
The target output output looks wrong or incomplete
Cause The source input input may contain unsupported syntax, corrupted data, or formatting that doesn't map cleanly to target output.
Fix Validate your source input input first, remove unsupported elements, and re-run the conversion.
Conversion seems slow or hangs
Cause Very large inputs or complex nested structures can slow down browser-based processing.
Fix Split the input into smaller chunks and process them separately.
Some characters change during conversion
Cause Character encoding differences between source input and target output can cause substitution.
Fix Ensure your source uses UTF-8 encoding before pasting it into the tool.
