My team is currently using a JIRA project to manage requests that we receive from various teams in the organization. We are then transporting this information for every ticket to a google spreadsheet and adding more information in the spreadsheet for every ticket. We realized that all of this information can be easily captured in the JIRA ticket itself. So we added additional fields to the JIRA project so all our existing tickets have these newly added fields but there is no information in these tickets against these new fields because this information exists in a google spreadsheet. Is there a way to bulk upload this information to the existing tickets in JIRA?
Just to explain it further,
I have a JIRA ticket, # XYZ1 that has 6 fields when the ticket was created. I added 10 new fields to the project XYZ so ticket #XYZ1 now has 16 fields. But the data for these newly added fields exist in a google spreadsheet that has 16 columns, 6 from the original ticket and 10 manually added columns. The names of 10 additional fields are the same as the 10 column headers in the google spreadsheet. Can I get the values of these newly added fields migrated to ticket #XYZ1 from the google spreadsheet without having to manually updated the ticket?
