Send me the spreadsheet (or just describe the control you need) and I'll build it or fix it: formulas and lookups, data validation, conditional formatting, pivot tables, automated summaries and a clean dashboard tab. I also turn repetitive work into one-click routines (Google Apps Script or Excel macros) and connect sheets to forms and exports.

What you get: a working file, a short note explaining how it works, and one round of revisions. Typical turnaround is 2 to 3 days; small fixes usually come back the same day.

Tell me what the sheet needs to do and who will use it, and I'll confirm scope and price before starting.
