I will clean and validate your excel, CSV, json, or sql data

Send me the file youve been avoiding.

Duplicates, missing values, inconsistent formats, broken encodings, invalid records, or messy CSV filesI can clean, validate, and organize your data while preserving the original dataset.

I work with Excel, CSV, JSON, and SQL data using Python, Pandas, and PySpark. For datasets too large for Excel, I can use scalable processing tools to handle larger workloads.

You will receive:

Cleaned and structured dataset

Duplicate detection and removal

Data correction and formatting

Missing and invalid value checks

Changelog of important transformations

QA report showing issues found and how they were handled

I document important changes instead of silently overwriting your data, so you know what changed and why.

Please provide your file, the columns or issues you want cleaned, and any validation rules or expected output.

For large datasets, multiple files, complex business rules, or custom requirements, please contact me before ordering for a custom offer.
