About this tool

Sort, reverse, dedupe, shuffle, trim and number lines of text with live line/word/character stats.

BrainCoder's text line tools let you manipulate lines of text with ease — add line numbers, remove blank lines, trim whitespace, sort lines, remove duplicates, and more. Whether you're cleaning up a list of data, preparing input for a script, or formatting text for a document, these line manipulation tools save you from tedious manual editing. Everything happens in your browser for instant, private results.

Working with lines of text is a daily task for developers, data analysts, and content creators. BrainCoder streamlines this with a suite of line-focused utilities: add sequential line numbers, strip empty lines from messy paste output, trim leading and trailing spaces from every line, sort alphabetically or numerically, and deduplicate entries. Each operation is one click away, with no need for command-line tools or complex text editors.

All processing happens client-side, so your data never leaves your device. This makes the tool ideal for working with sensitive data like API keys, configuration entries, server logs, or any text you don't want to upload. It's fast, free, and works on any device with a modern browser.
