We all aware about how to use the Vloookup function in Excel.

= vlookup (lookup value, table range, column index)

Now, we will use the same formula in UiPath to lookup the values.

Implementation in UiPath**

  1. Open the Excel file in UiPath using “Excel Application Scope Activity”, store the excel location in the variable . Lets say strExcelLocation.
  2. Read the range from the excel file using Read Range Activity from B6 to D10 & store it in a variable DTRange.

Hello,

FYI - UiPath actually has a VLookup activity https://docs.uipath.com/activities/docs/v-lookup-x

When you have thousands of rows in an excel, how would you do it without using for…each…row?

Sourav,

I’m afraid I don’t see a For Each Row in the original post. A Lookup Datatable activity is often used with some sort of Write Range, in order to update existing records. I’m afraid your question needs clarification and probably is better suited in a new thread of its own. Would you be against creating a new forum post of your own, where you can add the details of what you’re trying to do?

Thank you for your explanation, it was very clear, I will try it in my automation and then I will tell you about my experience.
