Messy spreadsheets in, clean reports out:
• deduplicate rows and fix inconsistent spellings, dates and number formats;
• merge multiple Excel/CSV files into one structured dataset;
• split or combine columns, remove empty rows, standardise categories;
• grouped summaries (by client, month, region) with totals;
• delivered as a tidy .xlsx plus the summary sheet you asked for.
Tell me what your data looks like and what you want out of it — I will confirm feasibility and timing before you order.
