2
Select your account
From the accounts dashboard, click the account you want to export — for example your Choice, Everyday, or credit card account.
3
Open the full transaction list
Click View all transactions or the Transactions tab to see your complete transaction history for that account.
4
Filter by date range
Use the date filter to select your period. For a first import, 3 months is a good starting point. Westpac supports custom date ranges.
Export each account separately — Westpac doesn't support multi-account exports in a single file.

Export as CSV
Click the Export or Download button above the transaction list. Select CSV as the format and confirm the download.
6
Import into Owdyn
In Owdyn, go to Accounts, select the matching account, click Import CSV, and upload the Westpac file. Owdyn maps Westpac's column format automatically.
