Choosing the right text tool
Text Tools on FreeMicroTools are for writers, students, online sellers and developers who work with plain text. Word Counter counts words, characters, sentences and reading time as you type, with limit bars for X posts, SMS, Google titles and Etsy titles. Case Converter changes text to UPPERCASE, lowercase, Title Case or Sentence case and cleans up extra spaces. JSON Formatter formats, validates and minifies JSON and shows the exact line and column of an error.
Use Word Counter when a platform, assignment or form sets a word or character limit. Use Case Converter to fix text typed with Caps Lock on, or to prepare headings in one consistent style. Use JSON Formatter when data from an API or a configuration file will not load and you need to find the mistake quickly.
Everything you type or paste stays in your browser and is never sent to a server, which matters for drafts, client text and data that contains keys or personal details. A JSON to CSV converter is on the roadmap.
