About this Gig

Need to turn a messy registration export into a usable contact list?


I organize structured Excel and CSV contact data for small teams and nonprofit coordinators. Choose Basic ($15, up to 100 rows), Standard ($20, up to 200), or Premium ($25, up to 300). Each covers one file, one worksheet, up to 10 input columns, 2-day delivery, and one in-scope revision.


I can split one consistently delimited field into up to three agreed columns, remove only exact duplicate rows, standardize agreed labels and clear dates, and flag missing or conflicting values. IDs and source values are preserved.


You receive a cleaned XLSX and CSV, original data, a change log, and a review list for anything uncertain.


Please message me with a small redacted sample and your required columns before ordering. Multiple files, mixed structures, guessed details, email verification, and CRM uploads are not included. Unclear values are flagged, never invented.
