Clean & Visualize Sales Data

I have several spreadsheets of raw sales data that need to be merged into a single, reliable source. Your first task is to remove duplicates, fix mis-aligned headers, standardise date and currency formats, and generally make sure every column is analysis-ready.

Once the data is spotless, I want clear, interactive visuals—think slicers, pivot-based charts, or a compact dashboard—built either in Excel or Power BI (I’m open to whichever tool you work fastest and most creatively in). When you’re done, include a concise handoff note that walks through the key formulas, any Power Query steps, and how I can refresh the visuals with new data.

Please highlight your experience doing similar consolidation and dashboard work; that’s the main thing I’ll use to choose the right freelancer.
