A hyperlinked value isn't retained in the Salesforce report export file.
Here are a couple workarounds that you can use to create hyperlinks in your Report export that link directly to Salesforce records.
Copying and pasting a report directly into Excel or Google Sheets is the best way to retain all hyperlinks. Exporting the report from Salesforce will remove the hyperlink and only display the text.
If the report is exported, it's possible to generate the hyperlinks via a formula directly in Excel. The information listed below only works when viewing the report via the Salesforce Classic User Interface and works best when applied to a report with less than 2,000 records.
Add the Record ID for the object that you want to hyperlink to when creating your report. After you export the report, you’ll add a new column and enter a formula to create a hyperlink to open the record in Salesforce Classic in your organization.
Example Scenario: The object Record ID is in column A of your report export.
Note: Replace instance_name in the URL above with the instance of your Salesforce org. For example: NA7 or EU13.
