I want to allow only excel type of attachment in jira , when there is another type of attachment i am able to stop the issue transistion by using JMWE app, but i don't want jira to take the attachment itself if it is not Excel. Is this possible by adding the validator to the attachmenmt field?
No, there's no way to do this. Validators don't apply to fields, and, even if they did, attachments is not a field.
You'd need to inject code into Jira's attachment field that could accept the upload, check the metadata to see what format the file is, and if it's not a recognisable spreadsheet, drop the file and tell the user that it's the wrong type. I don't think that it is currently possible to write something for Cloud that could do that.
