## Related tools

- [JWT Decoder](https://elysiatools.com/en/tools/jwt-decoder): Decode JWT tokens
- [JWT Generator](https://elysiatools.com/en/tools/jwt-generator): Generate JWT tokens with custom claims and algorithms
- [JWT Inspector & Verifier](https://elysiatools.com/en/tools/jwt-inspector-verifier): Decode a JWT (header + payload) with syntax highlighting, diagnose standard claims, and verify the signature with HS*/RS*/PS*/ES*/EdDSA keys — plus a tampered-token forgery demo
- [CSV/JSON Data Watermarker](https://elysiatools.com/en/tools/csv-json-data-watermarker): Inject visible or signature-style watermark fields into CSV or JSON exports so shared datasets can be traced later
- [JSON Key Extractor](https://elysiatools.com/en/tools/json-key-extractor): Extract all keys from JSON objects with multiple output formats. Perfect for analyzing JSON structure, documentation generation, and understanding complex nested objects.
- [AGEX Bundle Metadata Redactor](https://elysiatools.com/en/tools/agex-bundle-metadata-redactor): Rewrite exposed AGEX metadata like original filename or signer ID without touching ciphertext bytes
- [Dataset Quality Profiler](https://elysiatools.com/en/tools/dataset-quality-profiler): Profile CSV or JSON datasets for missing values, duplicate rows, format drift, type inference, and numeric outliers
- [ECharts Theme Token Extractor](https://elysiatools.com/en/tools/echarts-theme-token-extractor): Extract design tokens — colors, numbers, font sizes and strings — from an ECharts theme JSON and export them straight into your design system. Paste a theme object (the kind registered via echarts.init(dom, themeName)) and the tool walks every leaf, tagging each color (with optional named/rgb → hex normalization), spacing number, font size and string, then emits clean CSS variables, a Tailwind theme.extend config, Style Dictionary tokens.json, or SCSS variables. Bridges the gap between an ECharts visualization theme and Figma/CSS/Tailwind design tokens without copying each value by hand.
