How does a running-balance check find errors?

It compares the change between consecutive balances with the transaction’s expected signed effect, helping locate sign mistakes or missing amounts.

Can running-balance math prove the whole statement is correct?

No. Offsetting errors, rows without balances and systematic extraction problems can remain, so source and completeness checks are still required.

What is the safest way to apply this guide?

Start with an authorised, unlocked digital statement and a small representative period. Confirm the source layout, preserve the original file, review the resulting rows against the PDF and complete define the sign convention, calculate consecutive differences, inspect only supported balance rows, record explained exceptions before relying on the output.

Can this bank statement workflow be completely automatic?

Automation can reduce initial data entry, but it cannot remove source and review risk. Fees, interest, same-row multi-amount layouts or absent balances can make simplistic difference rules misleading. Keep a human review step for important financial use.

Which records should be retained after using this workflow?

Retain the original statement, a reviewed master export, correction or mapping notes, control totals and the destination-specific file under your authorised retention policy. These records explain how the source became the editable transaction table and source statement.
