Hey, for your purpose, the most effective way is to create the bank statement template in excel. This way you would be able to retain (or if required, modify) the layout of the statement and easily edit the data.
If you could share a sample PDF whose layout needs to be maintained, I would be able to create the excel template that you may use to manage the data as required. This project should not take more than a day to complete.
Thanks and Regards,
Shikha
