What the tool reads in a Wells Fargo statement
A transaction history with Deposits/Additions and Withdrawals/Subtractions columns and an ending daily balance printed only on the last line of each day. Amounts are unsigned, so each is placed by the column it sits under. Checks listed again in the summary of checks are not counted twice.
Before comparing anything, the tool adds the lines it read to the beginning balance and checks the result against the ending balance printed on the statement. If they disagree it says so, instead of guessing.
