Excel & CSV Data Cleaning with Quality Checksxinghui li
Prepare a reliable spreadsheet for reporting or your next analysis.
STARTING PACKAGE — US$75
One Excel sheet or CSV, up to 500 rows and 10 columns. Includes agreed text and category standardization, duplicate handling, date and numeric formatting, and checks for missing or invalid values.
WHAT YOU RECEIVE
A cleaned file, a separate list of unresolved or excluded records, and a concise quality report showing input/output counts and applied rules. Where useful, a repeatable AI-assisted script and instructions can be included within the agreed scope. One round of revisions to the agreed rules is included.
HOW WE START
Send an anonymized sample, the intended use of the data, and your required file format. We agree on the duplicate key, valid date formats, required fields, and treatment of missing values before work begins. Missing facts are flagged rather than invented, and uncertain records remain traceable.
DELIVERY
Target: two business days after scope and complete inputs are confirmed. Acceptance is based on the agreed cleaning rules, reconciled record counts, and a reviewable exception list.
Additional files, joins, OCR, complex statistical modeling, macros and integrations require a separate quote. This service uses AI-assisted analysis and programming; client data and AI use must follow the confidentiality requirements agreed before work starts.
