To export your transaction history, you must use the desktop version of Copay or BitPay. This is not supported on the mobile versions.
If you do not have your wallet setup on a desktop/laptop, then you can install the app and then import your mobile wallet to the device using the backup phrase from your mobile wallet. Please see this article for instructions on how to import your backup on a new device.
To export your transaction history from the desktop app:
- Select 'Settings' from the bottom menu
- Select the wallet to export ('Personal Wallet' is the default name)
- Select 'More Options'
- Select 'Transaction History'
- Select 'Export to file'
- Save the file to your computer.
The file will be exported as CSV file, which can be opened with any spreadsheet application.
If you need to export the transaction history for more than one wallet in your app, you will need to do the above steps for each wallet.
