Switching between multiple extensions or external tools for simple tasks like case conversion, Base64 encoding, or JSON formatting slows you down. quick-utils puts all of these common operations behind a single command palette entry, keyboard shortcut, or Activity Bar click — no context switching required.
- Text Transform: Convert selected text to UPPER CASE, lower case, camelCase, PascalCase, snake_case, kebab-case, Base64, or URL encoding — with multi-cursor support
- JSON Format / Minify: Format or compress selected JSON with validation before transform
- Code Generation: Generate UUID v4, Lorem Ipsum paragraphs, or insert formatted dates via a multi-step wizard
- Regex Tester: Interactive WebView panel for testing regular expressions with live results
- Operation History: Track all operations with relative timestamps in the sidebar
- Activity Bar: Dedicated tools panel with categorized tree view
- Localization: English and Japanese (l10n)
- File Watcher: Monitors
.quickutilsrc/.quickutilsrc.jsonfor project-level configuration changes - API Integration: Secure API key storage with automatic retry and progress reporting
- Open the Extensions view (
Ctrl+Shift+X) - Search for quick-utils
- Click Install

This extension is designed with security as a priority:
- API keys are stored in VS Code's built-in SecretStorage (OS keychain)
- WebView panels use a strict Content Security Policy (CSP) with nonce-based script execution
- All user input is validated before processing (JSON, Base64, regex patterns)
- No data is sent externally unless you explicitly configure and use the API feature
For security concerns, please see SECURITY.md.
- Make sure you have text selected in the editor
- Check that the file is not read-only
- The selected text must be valid Base64 (A-Z, a-z, 0-9, +, /, =)
- Length must be a multiple of 4
- Ensure the selection is valid JSON (not a fragment or JavaScript object literal)
- Trailing commas and single quotes are not valid JSON
- Check the Output panel (
View > Output > Quick Utils) for errors - Try closing and reopening the panel
Contributions are welcome! Please see CONTRIBUTING.md for guidelines.
If you're planning a larger change, opening an issue first is appreciated (it helps align direction and avoids duplicate work).
quick-utils is a personal hobby project maintained in spare time. I'll do my best to review issues and PRs, but responses and releases may be a bit slow sometimes — thank you for your patience.
Helpful things when reporting bugs:
- OS / VS Code version
- Your quick-utils settings (only what's relevant)
- Steps to reproduce + expected/actual behavior
Security-related reports should follow SECURITY.md.
