Hi @sayali_gujarathi1

  1. Check UiPath Project Dependencies: Ensure that your UiPath project is using the correct version of the “DocumentFormat.OpenXml” assembly. You can verify this by checking the “Dependencies” of your UiPath project.a. In UiPath Studio, go to “Project” > “Manage Dependencies” to view the project dependencies. b. Look for the “DocumentFormat.OpenXml” entry in the list and make sure it matches the version (2.5.5631.0) mentioned in the error message.
  2. Remove Duplicate Assemblies: Check your project and system for any duplicate or conflicting versions of the “DocumentFormat.OpenXml” assembly. Having multiple versions can lead to conflicts.a. In your UiPath project, ensure that there are no duplicate references to the “DocumentFormat.OpenXml” assembly. b. Check the packages installed in your project for any duplicate versions.
  3. Clear NuGet Cache: Clear the NuGet cache to ensure that UiPath fetches the correct versions of the required assemblies.a. In UiPath Studio, go to “Tools” > “Options” > “NuGet” > “General.” b. Click on the “Clear Cache” button to clear the NuGet cache.

Hope it helps!!

Check UiPath Project Settings: Verify that the UiPath project settings, including the project.json file, are correctly configured with the appropriate dependencies.

Hi @sayali_gujarathi1

  1. Check the version of DocumentFormat.OpenXml referenced in your project:
  • In UiPath Studio, go to the “Project Dependencies” panel (View tab > Project Dependencies).
  • Look for DocumentFormat.OpenXml in the list and check its version.
  1. Ensure that all dependencies and activities in your project are compatible with the version of DocumentFormat.OpenXml you have referenced.
  2. Update the DocumentFormat.OpenXml package:
  • If the version referenced in your project is outdated, consider updating the DocumentFormat.OpenXml package to a compatible version.
  1. Check dependencies of your activities and libraries:
  • If you are using custom libraries or activities that have dependencies on DocumentFormat.OpenXml, make sure they are compatible with the version you have in your project.

Hope it helps!!
