The Text Cleaner trims line edges, collapses consecutive spaces, removes empty lines, expands tabs to spaces, deduplicates matching lines, and forces uniform lowercase text directly in your browser.
Applies regular expression transformation pipelines to collapse consecutive spaces (`/ +/g`), expand tab characters (`/\t/g`), strip empty lines (`/^\s*[\r\n]/gm`), trim leading and trailing line whitespace, deduplicate duplicate lines using a Set collection, and optionally convert characters to lowercase.
