Step by step, and if something goes wrong

If something goes wrong

  • Amounts like £1,234.50, (12.00) and 12.00 DR become plain numbers; debits become negative.
  • A value that can’t be read with confidence is left exactly as it was and listed in the report. Nothing is guessed.
  • Keep “Remove duplicate rows” off if the same purchase can genuinely happen twice in a day.
  • Tick “Open in Excel” so the £ sign and accents show correctly in Excel.
