Workbook recovery route

A fragile workbook separated into source, refresh, checks and handover.

The team can rerun the monthly workbook with its source state, open checks, manual adjustments and owner notes visible before the output pack is discussed or handed over.

What is difficult now

Recurring Excel reports become fragile when source files, formulas, copied tabs, manual adjustments and output views are mixed together. Refresh steps become hard to explain, and review meetings can drift into fixing the workbook instead of using the information.

What needs to be decided

How can a recurring workbook be made safer and easier to update without first rebuilding the wider data platform?

What this page shows

A workbook routine with a source register, Power Query transformation route, validation checks, manual adjustment log, output pack and handover notes.

How the work fits together

The workbook separates inputs, Power Query steps, checks and output.

The sequence follows the monthly files through preparation and checking, then shows the output pack and notes needed for the next refresh.

What the review receives

  • Thirty-five grouped output rows
  • Twenty-five source rows requiring review
  • Status and owner notes beside the reported values
05Handover

Notes for the next update

  • Source naming and refresh steps documented
  • Manual adjustments kept outside formulas
  • Open checks and known limits retained for the next owner

Why this matters

The team can rerun the monthly workbook with its source state, open checks, manual adjustments and owner notes visible before the output pack is discussed or handed over.

Built from a non-client example dataset. No protected data is used.

A safer monthly update

Inputs, refresh steps and manual changes no longer compete inside the same workbook.

Separate source inputs, transformation steps, manual adjustments and the outputs people actually use.

  1. 01

    Two monthly exports provide 49 source rows, with the file owner and refresh context recorded alongside them.

  2. 02

    Seven preparation steps and seven validation checks separate 25 review rows from the grouped output.

  3. 03

    Seventeen flags and three manual adjustments are recorded outside the formulas and included in the handover notes.

Workbook checks

What loaded, what changed by hand and what is ready to issue.

Source route49 rows

Combines two monthly exports while retaining file, owner and refresh context.

Review state25 rows

Keeps rows requiring review visible before the output pack is used.

Manual adjustments17 flags

Separates flagged rows from the three-item adjustment register and formulas.

Grouped output35 rows

Produces a compact reporting output with status and owner notes beside the values.

Workbook contents

The sheets, source files and practical limits of the rebuild.

What is included

  • Source register
  • Power Query route
  • Validation checks
  • Manual adjustment log
  • Output pack
  • Handover notes

What it can start from

  • April and May CSV exports
  • Five-item source register
  • Seven-step preparation route
  • Validation register
  • Manual adjustment log
  • Handover notes

What this example does not claim

  • The workbook records a local file-based routine rather than a live shared-drive or scheduled refresh.
  • Open checks and adjustment treatment still require owner judgement.
  • Source naming, fields and update ownership would be agreed for a live workbook.

Power Query Consolidation Pack

What is difficult now
Monthly consolidation becomes unreliable when expected files are missing, columns drift and the folder refresh has no clear check or owner.
What the work helps decide
Which exports loaded, which file is missing, where column drift needs review and whether the combined reporting table is safe to use?
  • Power Query
  • Folder refresh
