About this Gig

Messy spreadsheets slow everything down: duplicate customer records, inconsistent date formats, blank fields, and data that won't match cleanly between files. If you're still fixing this by hand in Excel, it's costing you hours you don't have.


I clean, organize, and validate CSV and Excel data so it's actually usable: removing blank or invalid rows, standardizing formats and categories, fixing inconsistent entries, and deduplicating records.


What sets this apart from most data-cleaning gigs is custom matching logic. Instead of only removing exact duplicates, I can build matching rules specific to your data, for example matching records by date + amount + merchant, customer ID + email, or SKU + product ID, so near-duplicates and inconsistent entries get caught too.


Scope is tied to file count and row count per package, so you know exactly what you're getting. Very large datasets, non-tabular PDFs, or highly irregular formats may need a quick look before ordering.


Not sure which package fits your data? Send me a sample or describe what you're working with and I'll point you to the right one.
