About Text & Data Tools

Streamline your text processing and data manipulation tasks with our free online developer tools. The word counter analyzes text for word count, character count, sentence count, reading time, and keyword density, making it perfect for writers, bloggers, and SEO professionals. The password generator creates cryptographically strong random passwords using your browser's built-in crypto API, with customizable length and character types. Developers rely on our CSV to JSON converter for quick data format transformations, the Base64 encoder/decoder for handling binary data in text contexts, and the URL encoder/decoder for working with web addresses containing special characters. The regex tester provides real-time pattern matching with syntax highlighting and capture group extraction. For everyday text tasks, the case converter transforms text between uppercase, lowercase, title case, and more, while the lorem ipsum generator creates placeholder text for design mockups. Every tool processes data entirely in your browser for complete privacy and security.

Frequently Asked Questions

Q: Is my data processed locally and kept private?

A: Yes. All text and data processing happens entirely in your browser using JavaScript. Your text, passwords, CSV files, and any other data you enter are never uploaded to our servers or any third party. When you close the tab, all data is gone. This client-side approach ensures complete privacy, which is especially important for tools like the password generator and hash generator.

Q: What encoding formats are supported?

A: Our text and data tools support a wide range of encoding formats. The Base64 encoder/decoder handles standard Base64 and URL-safe Base64. The URL encoder/decoder supports percent-encoding per RFC 3986. The hash generator produces MD5, SHA-1, SHA-256, and SHA-512 hashes. The CSV to JSON converter auto-detects delimiters and supports custom separators, while the regex tester supports the full JavaScript regular expression syntax with all flags.
