How does one bulk "find and replace" the summary field?

[Mike Puckett]

I'd like to bulk edit the summary field of subtasks after they are created using a standard "find and replace" operation. Is that possible? If so, how?

Hi @Mike Puckett Welcome to the community!

If you want to bulk update the summary field then you can find out all the sub-tasks using the JQL and export it to CSV including the Issue Key, and Summary fields.

Update the summary on the CSV file and import it again 

At the time of mapping map the Issue Key and Summary 

It will update the Summary field.

This didn't work. While mapping, Issue Key can't be found in the drop down. Only Issue Key could be found.
