How does match personal expenses with the bank statement (reconciliation) ?

Every week I input my personal expenses from different channels (credit card, debit transaction,...) into a excel data base. This process results in a large database (2018, 2019,..). At the end of the each month I would like to have a way to match these excel database with the original statements from the bank/credit card to check if deviation for corrections (reconciliation). So, if the data matches...... the contents from "Account" and "Sub-Account" should be copied to the Statement. I started to work on but I can't get progress because of is not easy to connect/find the similar data. (I was thinking a way should be create a unique ID for both database...but it is just a idea)
I've added a attachment with more details (tab Flow & Explanation) about the request.
Thanks in advance for any support !
