First, pin down the gap
Look at the account in Xero and find the last transaction before the gap and the first one after it. Those two dates are what you need to fill — nothing more, or you'll create duplicates.
If the feed is still disconnected, get it reconnected first so new transactions keep flowing, then deal with the gap separately.
Fill it from your PDF statements
- 1
Download the statements covering the gap
From online banking, download the PDF statement (or statements) that span the missing dates.
- 2
Convert to Xero CSV with Ledger Pilot
Upload the PDF and download the Xero file. The statement is checked so the transactions add up from the opening balance to the closing balance, to the cent.

Trim it to the missing dates
A statement usually covers more than the gap. Open the CSV in Excel and delete the rows dated outside the gap, so you only import transactions the feed missed.

Import and reconcile
In Xero go to Accounting → Bank accounts, open the account's menu, choose Import a Statement and upload the trimmed file. Then reconcile the lines as usual.
