I will clean validate and organize your excel or CSV data

Do you have a messy Excel spreadsheet or CSV file that needs to be cleaned, standardized, and made reliable?

I will clean, validate, organize, and format your data according to clearly agreed rules while preserving the original file.

Services can include:

Removing duplicates using an agreed matching rule

Correcting inconsistent capitalization, spacing, dates, and number formats

Standardizing categories, columns, and data structure

Identifying blank, invalid, or inconsistent records

Organizing sheets, columns, headers, and tables

Validating row counts and checking for accidental data loss

Depending on your package, you will receive:

A cleaned Excel or CSV file

A concise report explaining the changes

A separate exception list for records requiring your decision

One item means one row or record. Please contact me before ordering if your project contains multiple files, multiple sheets, complex formulas, macros, sensitive information, or unclear cleanup rules.

My Mechatronics Engineering and control-engineering background helps me approach data work systematically and carefully. I confirm the scope before starting, communicate clearly, and never invent uncertain values.
