01
Only one person can maintain it
The logic sits in one person's head. A small change risks breaking formulas that several other sheets depend on.
Excel & Google Sheets
Excel and Google Sheets work that holds up.
Expert O'clock builds and repairs spreadsheets that a business depends on: templates, trackers, calculators, models, dashboards, and the macros that connect them. Every build is structured, tested, and documented so your team can maintain it.

Common starting points
The problem is rarely the tool.
The issue usually begins with unclear definitions, fragmented sources, or a manual process that no longer matches the business.
02
Manual copying creates errors
Data is pasted between files each week with no validation, version control, or check that totals still agree.
03
The file has outgrown its purpose
A tracker that started small now holds years of data, takes minutes to recalculate, and supports decisions it was never designed for.
Templates, calculators, and models
A dependable spreadsheet separates inputs, calculations, and outputs. We build templates and tools with protected formulas, data validation, clear labels, and a structure that survives new rows, new users, and next year's assumptions.
For finance and commercial work, that includes pricing and margin calculators, budget and forecast models, cash flow views, and scenario switches that show the effect of changing an assumption.
- Templates, trackers, and registers
- Pricing, costing, and margin calculators
- Budget, forecast, and cash flow models
- Scenario and sensitivity views
Dashboards and analysis inside the workbook
Not every reporting need justifies a BI platform. When the data is modest, the audience is limited, or the work already lives in a workbook, we build pivot-based dashboards, KPI summaries, and exception views directly in Excel or Google Sheets.
Where reporting outgrows the spreadsheet, we say so and set out the path to Power BI, Looker Studio, or a database, so the file is not forced to do work it cannot support.
- KPI and management summaries
- Pivot tables, charts, and slicers
- Exception and reconciliation views
- Analysis on existing workbook data
Macros and Apps Script with a maintenance path
We use VBA in Excel and Apps Script in Google Sheets to remove repetitive steps: importing files, cleaning formats, refreshing reports, generating documents, and distributing outputs. Scripts include error handling and a clear failure message rather than stopping silently.
We also say when a macro is the wrong answer. If Power Query, a standard formula, or a small database removes the need for custom code, that is the more durable option.
- Import, clean, and format routines
- Report refresh and export steps
- Document and PDF generation
- Validation and error handling
Built to be handed over
Every build includes a short written guide, a documented structure, and a walkthrough. Formulas and scripts are explained in plain language, and workbooks are versioned so changes can be traced.
The aim is a file your team can open, understand, and extend without depending on the person who built it.
- Written guide and walkthrough
- Named ranges and documented structure
- Tested against real sample data
- Version history and change notes

Frequently asked questions
Can you fix an existing spreadsheet instead of rebuilding it?+
Usually, yes. We review the structure, formulas, and failure points first. If repairing the file is cheaper and safer than a rebuild, we recommend that. A rebuild is only proposed when the current design cannot support the work.
Do you work in both Excel and Google Sheets?+
Yes. The right choice depends on how the file is used. Excel offers VBA and Power Query; Google Sheets offers shared access and Apps Script. We build in the tool that fits your team's environment and explain the tradeoffs.
Can you build a financial model?+
Yes. Budgets, forecasts, cash flow, pricing, and scenario models are scoped around the decisions the model must support and the assumptions that need to be visible and auditable.
When should a spreadsheet become a database or web app?+
When data volume, simultaneous users, permissions, audit requirements, or repeated manual consolidation exceed what a workbook can handle. We assess that honestly and, where needed, build the migration path.
How long does a spreadsheet project take?+
Most spreadsheet builds and repairs are scoped at one to two weeks. Larger models or multi-file tools depend on the number of inputs, rules, and outputs involved.
