You will get multiple datasets merged into one master table
Project details
I merge multiple related datasets into one structured master table.
This is useful when your data is split across different exports, systems, or sheets and you need one final table for reporting, analysis, or handover.
I work with structured datasets such as CSV files and related tabular exports. The goal is a reliable merged output.
This service focuses on merging multiple files or tables into a single, structured dataset while preserving relationships and data integrity.
If you also need cleaning or standardisation, I can handle that as a follow-up step depending on your needs.

About Millie
Data Cleaning & Consolidation Specialist
Reading, United Kingdom - 1:32 am local time
If you have multiple CSV or Excel files that don’t line up, columns that don’t match, duplicate rows, inconsistent naming, broken formatting, or data that just feels chaotic, that’s exactly the kind of work I do.
I clean and consolidate datasets so they’re structured, readable, and actually usable.
I don’t build dashboards.
I don’t do vague “AI strategy”.
I don’t overscope projects.
I take messy data and turn it into one clean, consistent master dataset.
That includes:
- Standardising column names
- Removing duplicates
- Merging multiple files or sheets
- Fixing inconsistent formats (dates, currencies, IDs)
- Structuring datasets so they’re analysis-ready
I work best with clear scope and defined outcomes. You send the files, explain the goal, and I’ll tell you exactly what I’ll do and when it’ll be delivered.
I prefer written communication and structured projects. No unnecessary meetings. No chaos.
If you want your dataset cleaned properly and without drama, I’m your person.
