In Admin Center click Account then Tools then Reports, then open the Export tab and pick full JSON export, CSV export, or XML export. Only account admins and custom agent roles with export permission can run it, the tools are not on Team plans, and the account owner must first ask Zendesk Customer Support to switch exports on. Zendesk emails a link to a zip valid at least three days; JSON comes as newline delimited NDJSON, and any ticket over 1 MB is exported without its comments.
What it holds
Customer support tickets with comment threads, plus end user and organization records.
Find the size
Admin Center shows no data size. Read the count in Zendesk Explore, where the Tickets dataset metric Tickets is defined as the total number of tickets, and note that Zendesk recommends JSON above 200,000 tickets and splits accounts over one million tickets into 31 day increments.
What to enter on the form
