The Monzo–Xero feed uses Open Banking and needs re-consent every 90 days. When it lapses (or during a Monzo outage), transactions stop flowing from that date.
After renewing, the days between the stop and now are still empty in Xero. Those have to be imported manually, cleanly, without duplicating what came through earlier.
Export a Monzo CSV for the missing period (Monzo app → Account → Export transactions → CSV), run it through the Monzo → Xero preset, and import. Names map to Description, dates are reformatted, signed amounts preserved — reconciles first time.
Export the CSV for the missing period, map it with the Monzo → Xero preset, download a clean file that reconciles. Free to start, client-side, nothing uploaded.
