Bank statement and cashbook reconciliation

[acube4gh]

I have two table: BANK STATEMENT and CASH BOOK Firstly, want to compare the amounts, if they are equal then Secondly, check the narration if at least three or four letters match, will pair them. If amount is equal but none of the narration matches, will unmatch them. I have attached an excel to explain it further and this is also an example
