About this collection

Clean and compare line-based data faster.

List tools turn pasted rows into useful output without opening a spreadsheet. Remove duplicates, sort entries, wrap every line with a prefix or suffix, change delimiters, or identify values that appear in only one list.

They work well for keyword lists, product identifiers, email exports, URL collections, inventory codes, and other small batches of line-based data.

Private by default: processing happens locally on your device, so pasted text is not uploaded to TextLumo.
