Should I delete duplicate-looking bank transactions in Excel?

Not without source evidence. Recurring payments can share a date, amount and description, so compare references and running balances before removing a row.

How should I store account numbers in Excel?

Use text formatting when leading zeros or long values matter, and keep sensitive identifiers masked where the work does not require the full value.

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 duplicate the reviewed sheet, define each transformation, protect reference fields as text, reconcile after every material change 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. Sorting, replacing or reformatting the only copy can destroy the trail back to extracted source values. 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 an Excel analysis, coding or reconciliation model.
