[IT]

Hello sir/madam,

I have an issue with reporting generator XLSX file:

- Version Telerik Reporting 18.2.24.806 (Q2-2024)

- version Telerik.Reporting.OpenXmlRendering 18.2

- version DocumentFormat.OpenXml 2.0.502

 

Output error here:

Telerik.Reporting.Processing.RendererNotAvailableException
  HResult=0x80131500
  Message=XLSX rendering format is not available.

Hi,

Thank you for the screenshots.

This error typically indicates that the Telerik.Reporting.OpenXmlRendering or Telerik.Reporting.OpenXmlRendering3 assembly/NuGet package is missing. Could you please confirm if you are referencing any of these assemblies in your project?

Note that when you use 'DocumentFormat.OpenXml 3.3.0' NuGet package, you have to install the 'Telerik.Reporting.OpenXmlRendering3'(with "3" at the end) NuGet package instead of 'Telerik.Reporting.OpenXmlRendering'.

Also, if you're using assembly references instead of NuGet packages, you can get the assembly from the installation folder - C:\Program Files (x86)\Progress\Telerik Reporting 2025 Q2\Bin.

More information you can find in this OpenXML and XPS options not visible. Unavailable rendering format - Telerik Reporting article.

I hope you will test it and keep us updated.

Regards,
