The Text & Writing category includes free tools for counting, cleaning, and converting text so writing, editing, and data work go faster. From staying within character limits to tidying messy pasted text and converting between data formats, you can handle it here.
Tools in this category：12 tools
Writers and students use word and character counts to meet length limits, while anyone organizing data can clean blank or duplicate lines and sort content. For developers, JSON formatting, Base64, URL encoding, and CSV/JSON conversion save manual effort. Everything runs locally, so pasted text is never sent to a server.
Category navigation review:
A category page should shorten the decision, not make you try every tool. Write down the required output first, then compare input data, privacy needs, file format, reversibility, and the cost of checking the result. Similar names can describe different stages of a workflow, so choose by task boundary.
Count words, characters, lines, paragraphs, and reading time live for essays, posts, and length-limited copy. This is the stronger fit when the input is defined and that output is the actual goal. Before real work, use a small sample to confirm fields, units, interaction, and download format.
Count characters, UTF-8 bytes, words, and lines against common platform limits before you post or submit. If your problem is closer to this description, do not force the first-ranked option. Compare required source material, whether content is transformed, and whether the result remains editable.
Convert text between upper, lower, title, and sentence case in one click for titles, code, or imports. This option is a reminder that the task may need a different output type. After choosing, read that page’s limits and verification method, then test the result in the actual destination.
