CSV and Excel Data Cleaning
China

Sobre mí
I focus on rule-based CSV and Excel table cleanup, including text standardization, exact-duplicate removal and clear issue reports. My workflow keeps the original input unchanged and records cleanup decisions so you can review the result. I use AI-assisted code where appropriate and check outputs against the agreed rules. My portfolio sample uses synthetic data.
