Project details
I will clean, normalize, and validate messy CSV/Excel files so you can load them into dashboards, databases, or scripts without errors.
What you get:
• Cleaned CSV/XLSX outputs (consistent headers, dates, numbers, blanks handled)
• Robust fixes for common real-world issues: delimiter mismatches, mixed date formats, currency/decimal commas, missing/invalid values
• A clear log/report of what was changed (Starter: quick log; Standard: QC summary; Advanced: detailed QA + custom rules)
How I work:
1. Quick review + confirm your expected output format
2. Clean + normalize your data
3. QC checks + deliver cleaned files + included report/log
4. Apply included revisions (if any)
Large datasets are supported via workload add-ons (based on single file size or total batch size). Upload your files (or a sample) and tell me your preferred output format.

Review files + confirm output
I review your files and confirm the target output (format, dates, decimals, delimiter) and any rules you provided.
Clean + normalize data
I clean and normalize headers, missing values, dates, and numbers/currency, then generate the cleaned output files.
