I will clean merge split and process large CSV excel json XML data

Are you overwhelmed by messy, fragmented, or massive data files? If you are exhausted from manually combining, cleaning, and formatting your CSV and Excel exports, you are in the right place.

I specialize in handling complex, large-scale data manipulation, file merging, and data cleaning. Whether you have hundreds of small identical files or massive, completely different exports from CRMs (HubSpot, Salesforce) or E-commerce platforms (Shopify, Amazon), I will deliver a clean, structured master file.

What I can do for you:

Merge & Consolidate: Combine hundreds of CSV, XLSX, or TXT files into a single master sheet (even if columns don't perfectly align).

Data Cleaning & Deduplication: Remove duplicates, fix broken formatting, split combined columns (e.g., Names/Addresses), and handle missing values.

Big Data Handling: Split massive CSV files into smaller, organized sheets based on your custom rules.

Supported Formats: CSV, Excel (XLS, XLSX), TXT, JSON, XML.

No dataset is too large or too messy.

Drop me a message with your file samples before ordering, and let's get your data perfectly organized!
