The official Jira Cloud for Sheets add-on still works but has been unreliable since the Dec 2024 API change, and most alternatives charge per user. Sheet Sync for Jira runs JQL or saved filters into Google Sheets with every field including custom ones, pages through full results instead of stopping at a cap, and refreshes hourly, daily or weekly. Flat US$20/month per Jira site. It runs in Apps Script - no vendor server touches your data.
