Validation and compatibility
The registered HTML parser checks that the input can be read into the route's table model. A parsing error stops conversion before target output is created. Validation confirms that this converter can read the input; it does not guarantee compatibility with every third-party application that may consume the result.

Accuracy and limitations
Some formatting, types, nested structure, or metadata may be normalized during conversion.
Privacy and safe processing
Supported files and pasted content are processed in the current browser tab. The converter does not execute generated PHP, Ruby, SQL, DAX, Qlik, ASP, ActionScript, or other source code.
