Validation and compatibility
The registered Excel / XLSX 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.
- Recommended browser-processing size: 25 MB
- Streaming support: Not available for this route
- Workflow use: Eligible when adjacent route models are compatible
Accuracy and limitations
Values supported by both formats are retained through the shared conversion model. Format-specific whitespace, ordering, layout, formulas, metadata, or data types may be normalized when the target has no equivalent representation.
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.
