I analysed multi-channel marketing campaign data to evaluate campaign performance, spend, conversions and return on investment. I cleaned and structured the data, calculated key metrics including click-through rate, conversion rate and cost per acquisition, and used Excel formulas, PivotTables and charts to compare performance across channels and campaigns. I then created a dashboard highlighting key findings and areas for improvement to support future marketing decisions.

Excel PivotTable — Sales Summary
Client had raw sales data (14 rows across UK/USA, split by quarter) and needed it turned into something actually usable. I cleaned it up and built a PivotTable that breaks total sales down by rep and country, with grand totals for both.
What I did:
Structured the raw data into a proper table (consistent headers, currency formatting)
Built a PivotTable summarizing Sum of Sales by Last Name and Country
Used SUMIFS so the totals update automatically if the source data changes — nothing hardcoded
Checked every formula for errors before delivery
Delivered as a working .xlsx file, ready to plug into a bigger report or dashboard.
If you've got messy sales/ops data sitting in a spreadsheet and need it turned into something you can actually read at a glance, this is exactly the kind of thing I can help with.
