I help run scoring for a small CS scrim league and our old match logs are a mess — duplicate player names, mixed date formats, half the rows missing winner info. Cleaning it manually has been brutal. While reading up on this for work I bumped into a data quality consulting page that walks through how bigger companies handle the same thing at scale, and turns out the patterns repeat. Anyone here got a decent workflow for normalizing player names across seasons, or do you just live with the noise?
