How can i export tickets data in excel in one go. As there is a limitation on JIRA for 1000 ticktes at a time ?

[Nic Brough -Adaptavist-]

And on top of both of those answers remember that the limit is there for a reason - if you go too high, you will render your JIRA unusable, and get a timeout.

Unless you have a smallish JIRA, you're wasting your time here.  It would be far better to ask why you want to do this export, and work out better way tog get to the end result.

[Michael Kornatzki]

you can change the limit in system - advanced settings - jira.search.stable.max.results
