Data Cleaning & Preparation

Structured data cleaning using Python (Pandas) and Power Query to turn raw files into reliable, analysis-ready datasets.

Raw data from exports, spreadsheets, and accounting systems is rarely ready to use. Duplicate rows, inconsistent formats, merged cells, and blank fields slow down analysis and create reporting errors. This service takes your raw files and returns clean, structured datasets — validated, formatted, and ready for Power BI, Excel reporting, or further analysis. Work is done in Python (Pandas) or Power Query depending on your stack and volume.

What's Included

Duplicate detection and removal
Inconsistent formatting standardised (dates, names, codes)
Blank and null value handling
Column structure and header cleanup
Data type correction (text treated as numbers, etc.)
Merge and consolidation of multiple files
Xero export preparation for Excel reporting
Power Query transformation setup for repeatable refresh
Python (Pandas) scripts for large or recurring datasets
Delivery as clean Excel file or structured CSV
