Slate
Private Text & Code Toolkit
Formatting JSON, decoding Base64, and transforming text shouldn't mean handing sensitive data to an online tool. Slate gives you a collection of handy tools for working with text, code, API responses, and logs—all directly in your browser, without sending your data to a remote processing server.
CORE CAPABILITIES
Powerful Tools. Your Data Stays Private.
Private, Browser-Based Processing
Work with sensitive text, API responses, configuration files, and code directly in your browser. Slate processes your content locally without sending it to a remote processing server.
30+ Text & Data Tools
Convert JSON to YAML, CSV to JSON, encode and decode Base64, hexadecimal, and URLs, find and replace text, change letter case, remove duplicate lines, and sort content—all in one place.
Smart Code Editor
Edit and format code with syntax highlighting, automatic bracket matching, and support for 15+ programming and markup languages, including TypeScript, Python, Rust, SQL, and Markdown.
Local Workspace & Multi-Document Support
Keep multiple documents open in separate tabs and pick up where you left off. Your work is saved in your browser's local storage and remains available across page reloads, with support for offline use when the required resources are already available.
