Reading PDF with ocr

Help Studio

I have tried to read invoice with read pdf text with OCR engine. Am not able to drag and drop any OCR engine. Can any one help me please.

Hi @Vanitha_VS,

This usually happens when the OCR packages are not installed in your project. Can you check?

Additionally, Can you share snapshot of the issue?

Thanks!

It sounds like you are likely using a newer version of UiPath Studio (v2022.10 or later) or working within a Cross-Platform project. In recent updates, UiPath changed how OCR engines are handled to make them more integrated and easier to manage.

Here is how to resolve the “drag and drop” issue and get your invoice processing working:

1. Check your Project Compatibility

If your project is set to Cross-Platform (usually for Linux/Cloud robots), many older “Engine” activities are not compatible.

  • The Fix: Look for the UiPath.OCR.Activities package in your “Manage Packages” window. Ensure it is installed.
  • The Tool: Use the OCR - Extract Text activity or Read PDF with OCR and look at the properties panel rather than trying to drop an engine into the activity body.

2. The Modern Way: “Read PDF With OCR”

In modern versions, you don’t always “drop” the engine into a box. Instead, the activity has a placeholder or a property.

  • Search for Read PDF With OCR in the Activities panel.
  • If there is a plus sign (+) or a “Drop OCR Engine here” indicator, search for UiPath Document OCR, Tesseract OCR, or OmniPage OCR in the Activities panel.
  • Note: If you don’t see these engines, go to Manage Packages > All Packages and install UiPath.UIAutomation.Activities
