Excel Currency Format Normalization

I have an Excel workbook in which numeric entries are a mess—some are real numbers, others are text strings littered with stray symbols, and quite a few mix commas and periods as decimal separators. I need every monetary figure, in every column that contains numeric data, converted so it behaves as a true number and displays in a single, consistent currency style: the $ symbol with two decimal places.

Your task is to hunt through the file, detect any value that should be treated as money, automatically recognise whether the comma or the point is acting as the decimal marker, correct it, and then apply the chosen format. Dates, percentages, text, formulas, and the workbook’s structure must stay exactly as they are; after the cleanup nothing should break or recalculate incorrectly.

Deliverable
• A cleaned .xlsx file in which every relevant cell shows the proper $ currency format, ready for immediate reporting or further analysis.
