I will fix broken google and excel spreadsheets and formulas

Is your spreadsheet giving the wrong answers, behaving inconsistently, or doing something that makes no sense?

I specialise in fixing and debugging existing Google Sheets and Microsoft Excel files. This service is for spreadsheets that almost work, but not quite incorrect formulas, broken logic, confusing conditional formatting, or date-based rules that dont behave as expected.

Typical issues I fix include:

Formulas returning wrong or inconsistent results

Conditional formatting not applying correctly

Date logic (e.g. UK tax year rules)

Lookups, filters, and totals that dont add up

Sheets that work for some rows but not others

I focus on repairing and simplifying what you already have, not rebuilding from scratch. Where helpful, Ill also explain what went wrong so you can avoid the same issue again.

This is a fix/troubleshooting service, not data entry or dashboard design.

Works with:

Google Sheets

Microsoft Excel (formula-level support)

Before ordering

Please send a message first with:

A brief description of the problem

The spreadsheet file or a shareable copy

What result you expect vs whats currently happening

I dont use VBA, macros, or Power Query unless explicitly agreed
