The short version
Why this work usually gets commissioned.
Data cleaning done once is a favour. Data cleaning done as a repeatable process is an asset. The difference is whether the transformation is written down as steps that can run again next month, or performed manually by someone who will not remember exactly what they did.
Scope
Data cleaning, Power Query and analysis: what is included.
Every engagement gets an hours estimate before it starts. If something below is not relevant to you, it comes out of the scope and off the estimate.
Deduplication and matching
Fuzzy matching across sources that never quite agree on how a name is spelled.
Reconciliation
Finding where two systems diverge and, more usefully, why.
Analysis and reporting
Pivots, statistical summaries and the analysis that answers the question you actually asked.

Same work, different job titles
What people call this work.
These all describe the same engagement. The title matters less than whether the person writes things down — but it is worth knowing which term to search, because the results differ.
Data cleaning specialist
Takes messy exports and makes them usable — and, done properly, leaves you able to repeat it next month yourself.
Excel data analyst
Where the brief includes drawing conclusions, not only preparing the data for someone else to analyse.
Data wrangling or data preparation expert
The same work under names borrowed from the analytics world.
Power Query specialist
Named for the tool. Power Query is usually the right answer for repeatable cleaning in Excel, and it beats a macro for this.
Method
How we run it.
- 01
Profile the data
What is actually in there, including the things nobody mentioned.
- 02
Define the rules
What counts as a duplicate, what happens to a blank, how a bad date is handled — written down and agreed.
- 03
Build it repeatable
Power Query or a script, so next month is a refresh rather than a repeat.
- 04
Document the exceptions
The records that could not be resolved automatically, listed rather than quietly dropped.
- DiscoveryUnderstanding the decision the file supports, and who edits it.
- PrototypeA working version on your real data, while changing course is still cheap.
- BuildThe main work, against definitions agreed in writing first.
- TestingEdge cases, checks that fail loudly, and the numbers reconciled.
- HandoverDocumentation, update procedure and a recorded walkthrough.

Questions
Data cleaning, answered.
What clients ask before commissioning this work.
Ask us something elseHow much data can Excel handle?
A worksheet holds just over a million rows, but practical performance degrades well before that with heavy formulas. Power Query handles far more because it processes outside the grid. Past a few million rows you want a database, and we will say so rather than optimising a doomed approach.
Can you clean data with inconsistent names and spellings?
Yes — fuzzy matching handles most of it. The important part is that we surface the ambiguous matches for a human to decide rather than guessing silently, and we document what rule was applied.
Will I be able to run it again myself?
That is the point. Power Query steps are visible and rerunnable, and we document the process. If you would rather we run it each cycle we can, but you should not need us to.
Can you work with data from multiple systems?
Yes, and reconciling sources that disagree is a common engagement. Often the most valuable output is the explanation of why they differ, not the merged file.

Most engagements touch more than one of these. We scope them together rather than selling them separately.
