8 Powerful Developer Tools — Formatter · Minifier · SQL · JSON · Regex · Markdown · Base64 · URL
CalbTools brings commonly used coding utilities together in one place. Use these browser-based tools to clean up code, inspect data formats, test patterns, and encode or decode text while working on websites and software projects.
Format HTML, CSS, and JavaScript to make code easier to read and maintain. Paste your source into the formatter, choose the language, and generate a neatly indented version that you can copy or download.
Minify supported JavaScript code to reduce unnecessary whitespace and make the output more compact. Review the result and test it in your project before publishing changes.
Format JSON into a readable structure, minify it when a compact representation is needed, and check whether the input is valid JSON. The tool also displays basic information about the parsed data when available.
Check common SQL syntax patterns and format SQL statements for readability. This utility is intended as a lightweight helper; it is not a substitute for testing queries against your actual database engine.
Try a regular expression against sample text and adjust flags such as global, ignore case, multiline, and dot-all. Use the results to review matches before applying a pattern in your application.
Write Markdown and preview the rendered result. Copy the Markdown source or generated HTML, or download the content as a Markdown file.
Encode and decode text using Base64, or encode and decode URL components. These utilities help with common development tasks, but encoding is not encryption and should not be used to protect confidential information.
Privacy note: The tools are designed to process input in your browser. Some features load third-party JavaScript libraries from public CDNs, so an internet connection may be needed for those libraries to load. Avoid pasting passwords, API keys, personal data, or other secrets into online tools.
Yes. The tools on this page are presented for free browser-based use, with no account required by this interface.
The layout adapts to smaller screens. For long code samples, a desktop or tablet may provide a more comfortable editing experience.
No. Base64 is an encoding format, not encryption. Do not use it to conceal sensitive information.
No tool can guarantee search rankings. This page provides developer utilities; search visibility also depends on crawlability, helpful content, site quality, competition, and other factors.
