About this Gig

Need a tidy spreadsheet or several files combined into one? I will clean your Excel or CSV data using agreed rules and check the result before delivery.

Included:

Remove exact duplicate rows and extra spaces.

Standardize dates and numbers where the intended format is clear.

Combine files with matching columns (Standard and Premium).

Deliver the cleaned file and a brief summary of changes.

Packages:

BASIC: 1 file, up to 100 rows in total.

STANDARD: Up to 2 files, up to 200 rows in total.

PREMIUM: Up to 5 files, up to 500 rows in total.

Each package covers one table per file, up to 20 columns. One item means one input data row, excluding headers. All packages include one revision within the original scope.

Please provide your files and explain the desired result, duplicate-removal rules, and preferred formats. Ambiguous values will be flagged for clarification, not guessed.

This service does not include researching missing values, correcting factual errors, repairing formulas, macros, or combining tables with different structures.

Please message me before ordering if you are unsure which package fits. Share only data you are authorized to provide.
