Excel Data Entry Cleanup

I have an existing workbook that needs a tidy-up from top to bottom. Your first task is to key in a batch of raw data with zero transcription errors, remove any blank or duplicate rows, realign columns where headings or values have drifted, and generally make sure every cell is in the right place.

Once the information is clean, I’d like the sheet formatted for quick reading: headings that stand out, columns auto-sized, clear number and date formats, and any simple visual touches (for example basic colour highlights or borders) that make patterns jump out without becoming cluttered. If you spot a chance to add light data validation, a summary formula, or a pivot table that boosts usability, include it and note what you changed.

Deliverable: the fully cleaned and reformatted .xlsx file plus a short change log outlining the key fixes you applied so I can follow the workflow and replicate it on future updates.
