If you do not have the extension,    login to Company 0,  or your first company that you setup (which you should keep neutral for setting up additional companies),  FA...Setup...Install/Activate extensions...Import Transactions.  In the dropdown box FA... Setup...Install/Activate extensions...Extension:....SELECT 'Activated for' ... the relevant company (which should not be company 0). Activate this extension for this company. Logout of Company 0. Login to the relevant company.

Use the template under FA...Banking and General Ledger...Maintenance...Import Transactions...Journal Processing...Display...Display Help Notes...Point 6...Template

(Remember, if you are not using British chart of accounts, to change the account codes used in this template. )

Use the 'Trial check' before performing the import to make sure that you are happy with the overall process.

NB: You cannot process bank related journals using this extension. So no transaction using a bank account code will be allowed using this extension. You must use Import Transactions...Deposit/Payment Processing for this purpose.
