Why convert to lowercase
Lowercasing is a quick fix for accidental caps lock, and a common step when preparing data. Tags, URL slugs, hashtags and email addresses are usually stored lowercase so that duplicates match, and case-insensitive comparisons are simplest when both sides are lowercased first.
Lowercase for tidy, matchable data
If you are building a list of keywords or emails, mixed casing hides duplicates — Info@site.com and info@site.com look different to a computer. Lowercasing everything first, then removing duplicate lines, gives a clean, deduplicated set.
