HTML to EXCEL convert failed with error Invalid '#'

there is another thing we noticed recently:

  • when converting HTML to Excel we always get the failed error as
    • Convert failed - com.aspose.cells.CellsException: Invalid ‘#’(Based on Name Team Self-Assessment!print_area)
    • Convert failed - com.aspose.cells.CellsException: Invalid ‘#’(Based on Name BCM_NOK_poziomo!print_area)
  • we tried the same file with your online converter, we get the same error

  • This seems to cause by the Unicode recognition problem($ symbol i think)
    Thanks for advance.

Generally, we fix issues in .NET APIs first and then include fixes in Java version (source code is ported from .NET codebase) in parallel. We will also fix the issue in Java release.
