Free Online Text Tools

Reading Time Calculator Estimate how long any text takes to read or speak at different speeds. Typing Test Measure your typing speed in WPM with real words, multiple durations and a leaderboard.

Formatting & Conversion

The Delimiter Converter is the site's flagship: it splits a column of text by newline, comma, tab, pipe or any custom separator, then joins it back with the separator you need — ideal for building SQL IN clauses or converting between CSV and TSV. The Case Converter switches text between six capitalisation styles, and the Slug Generator turns headlines into clean URL slugs with accent stripping and stop-word removal. For anything more surgical, the Find & Replace Text tool chains search-and-replace, transform, extract and encode operations in one pass.

Counting & Analysis

The Word Counter, Character Counter and Line Counter analyse text as you type — words, characters with and without spaces, sentences, paragraphs, bytes and lines. The Reading Time Calculator converts a word count into minutes of reading or speaking time at adjustable speeds.

List Clean-Up

Sort Lines orders any list alphabetically or numerically (or reverses and shuffles it), and Remove Duplicate Lines deduplicates a list while preserving the original order — with a second panel showing exactly what was removed.

Typing

The Typing Test measures your WPM and accuracy with real words and sentences across durations from 15 seconds to 30 minutes, with three difficulty levels and a public leaderboard.
