The short version
Why this work usually gets commissioned.
There is a category of spreadsheet that runs a real part of a business and that everybody is slightly afraid of. It works, mostly. One person understands it. It has grown by accretion for four years. This is the work we do most: making that file reliable, reviewable and transferable without losing what made it useful in the first place.
Scope
Excel consulting, audits and spreadsheet rebuilds: 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.
Model rebuilds
Restructuring so assumptions live in one place, calculations are traceable, and a reviewer can verify the output unaided.
Formula and error debugging
Finding why the number is wrong, and more usefully, why nobody noticed for three months.
Second opinions
An independent read on a model before you rely on it for a decision, a bid or an investment.
- Constant inside a formula
- Reference to a closed file
- Circular calculation
- Manual step, undocumented

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.
Excel consultant
Advisory framing: someone who tells you what is wrong and what it would cost to fix, before touching anything.
Excel specialist or spreadsheet expert
Broader terms, often used by people who are not yet sure whether they need an audit, a rebuild or just a second opinion.
Spreadsheet consultant
Used where the stack is mixed — some Excel, some Sheets, some CSV exports nobody owns.
Excel auditor
Specific to reviewing a model or workbook for errors and risk, usually before someone external relies on it.
Method
How we run it.
- 01
Inventory the file
Every external link, every constant embedded in a formula, every manual step in the update procedure.
- 02
Prioritise by risk
Not everything needs fixing. We rank findings by what could actually cause a wrong decision.
- 03
Fix or rebuild
Sometimes a targeted repair is right. Sometimes the structure is the problem. We tell you which, and why.
- 04
Document ownership
Who maintains it, how it updates, and what to check before trusting the output.
- 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
Excel consulting, answered.
What clients ask before commissioning this work.
Ask us something elseWhat does an Excel audit cost?
A single-workbook audit is usually 4–8 hours at our standard hourly rate, delivered as a prioritised findings list plus a recorded walkthrough. You can act on it yourself or have us do the remediation — there is no obligation to continue.
Do I need to send you real data?
Often not. Structure and a representative sample are usually enough. Where real data is needed we sign an NDA first and can work from an anonymised copy.
Can you make our spreadsheet audit-compliant?
We can substantially harden a workbook — controlled assumptions, protected formulas, failing checks, documented procedure. Whether that satisfies a specific regulatory standard depends on the standard, and anyone promising blanket compliance for a plain Excel file is overselling it.
What if you think we should not be using Excel?
We tell you. It happens regularly, and it costs us the engagement. It is still the right answer when the honest recommendation is a database, a proper application, or a process change rather than a better spreadsheet.

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