What you get with this Offer
Need your Google Sheets to do more than standard formulas allow? I'll write custom Google Apps Script functions and validation rules so your spreadsheet works exactly the way your business needs.
What's included:
- Custom functions you can call directly in cells (just like =SUM() but built for your use case)
- Advanced data validation rules — restrict inputs, show warnings, enforce formats
- Input sanitisation scripts — auto-format text, dates, phone numbers, etc. on entry
- Custom dropdown menus or buttons for common tasks
- Conditional logic beyond what standard Google Sheets allows
Examples of what I can build:
✔ A custom =VATCALC() formula for your pricing sheet
✔ Validation that prevents duplicate entries in a column
✔ A button that clears only specific cells on click
✔ Auto-formatting names to Title Case or phone numbers to a standard format
✔ Multi-step conditional dropdowns (e.g. selecting a category auto-populates the next column)
Just describe what you need and I'll deliver it within 2 days.
