Full Description
I will clean your data and prepare it for analysis. Your data will be uniform and easier to read.
Tier 1: This foundational data cleaning tier is designed to quickly and accurately strip away the visual noise and structural anomalies from your datasets, delivering a clean, uniform, and immediately usable file.
Basic data formatting and structural integrity. Drop duplicates, standardize basic casing (uppercase/lowercase), strip whitespace, and fill or drop NaN values.
This tier is the perfect, high-efficiency solution for businesses, marketers, and researchers who have relatively healthy data that just needs a professional polish. It easily supports large-volume files making it ideal for raw CSV exports, lead generation lists, and basic financial logs.
Row Limit: 20,000
*Tier 2: This Tier is specifically engineered to tackle datasets suffering from severe human error, structural anomalies, and categorical inconsistencies. Using advanced, script-based data wrangling logic, I go beyond basic foundational formatting to actually audit and standardize the underlying integrity of your information. I transform chaotic, unpredictable entries into clean, uniform categories that your analytics software can reliably process.
Fixing human error, chaotic text, and structural anomalies. Correcting typos, standardizing phone numbers and messy dates, and ensure data types match the column headers.
This service is the ultimate sweet spot for businesses, researchers, and project managers dealing with datasets sourced from external surveys, merged departmental files, or inflexible legacy software exports. If your data requires more than just a quick formatting wash—if it needs actual logical restructuring and anomaly resolution—this is the exact tier for you.
Row Limit: 20,000 rows
Because chaotic data can be highly unpredictable, please send a brief message with a small sample of your dataset (roughly 50 rows) prior to booking. This required preliminary data audit ensures I can map out the exact logic needed to completely rescue your files.
Supported input file formats CSV and Excel. Others may be possible, please ask.
An activity log may be provided upon request.

Candy Work
I was tasked with cleaning a very messy dataset. I was able to fill and or remove all blank spaces, unneeded information was removed. Various country names were standardized. Age ranges were established rather than individual ages. Text was made bold and wrapped in the final product.
