Free Online Tools for Developers

Everyday developer chores should not need an install. These handle formatting, converting and encoding in the browser.

JSON

Markup and encodings

Things to remember

  • Base64 and the other encodings are not encryption.
  • These tools run locally, but avoid pasting live credentials into any web page you do not control.
  • The HTML entity tool handles five named entities and numeric ones, not the full named list.
  • The JSON tools follow the standard: no comments and no trailing commas.
