Free Online Text Tools

Every tool here works the same way: paste, get your result, leave. No account, no limits, no install, and nothing you paste is stored.

Not sure which tool? Working out how long something is, use a counter. Changing how a list is separated, use the delimiter converter. Tidying a messy list, start with list clean-up.

Delimiter Converter Split and join lists with commas, tabs, pipes, semicolons or any custom separator. Find & Replace Text Search and replace, transform, sort, extract and encode text with chainable operations. Word Counter Count words, characters, sentences, paragraphs and unique words in real time. Character Counter Count characters with and without spaces, letters, bytes and lines as you type. Line Counter Count total, blank and non-blank lines in code, CSV exports and plain text. Case Converter Switch between UPPER, lower, Title, Sentence, toggle and random case in one click. Slug Generator Turn titles into clean, SEO-friendly URL slugs with accent stripping and stop-word removal. Sort Lines Sort lines alphabetically or numerically, reverse them, or shuffle a list. Remove Duplicate Lines Deduplicate any list while keeping the original order, with case-insensitive matching. 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.

Choosing between formats

Before converting, it helps to know which format you actually want. The format comparisons answer that in a table: CSV vs TSV, comma vs semicolon and WPM vs CPM.

Formatting and conversion

Delimiter converter

The flagship. It splits a column by newline, comma, tab, pipe or any custom separator, then joins it back with whatever you need. Most people arrive here to build a SQL IN clause or flip a file between CSV and TSV.

Case converter and slug generator

The case converter switches between six capitalisation styles in one click. The slug generator turns a headline into a clean URL, stripping accents and stop words along the way. They pair well: fix the case first, then generate the slug.

Find and replace

For anything more surgical, find & replace chains search-and-replace, transform, extract and encode steps in a single pass.

Counting and analysis

Four counters, four different questions. The text counters hub explains which one matches which limit.

Word counter — words, sentences, paragraphs and unique words, live as you type.
Character counter — with and without spaces, plus UTF-8 bytes for database columns.
Line counter — total, blank and non-blank lines, plus longest line.
Reading time calculator — minutes to read silently, or to say out loud.

List clean-up

Sort lines orders a list alphabetically or numerically, or reverses and shuffles it. Remove duplicate lines deduplicates while keeping the original order, with a second panel showing exactly what it took out. The list clean-up hub has the order to run them in — it matters more than people expect.

Typing

The typing test measures WPM and accuracy using real words and sentences, at lengths from 15 seconds to 30 minutes and three difficulty levels. Save a score and you land on the public leaderboard.
