Clean up JSON, make it readable, minify it for transport, and catch syntax errors before you paste it elsewhere.
Tool category
Developer and data tools
These eleven tools help inspect or transform structured data and development artifacts. Parser dialects, signature-verification boundaries and unsupported formats are stated on the relevant page.
JSON Tools
Compare two JSON values and list added, removed, changed, and unchanged paths after validating the JSON input.
YAML, XML & CSV Tools
Convert JSON and a documented basic YAML subset in either direction without uploading the text.
Encoding & Decoding
Encode text to Base64 or decode Base64 back to readable text in your browser.
Regex & Parsers
Test JavaScript RegExp patterns against text in your browser with match count, indexes, syntax errors, and input length limits.
Parse and explain common 5-field cron expressions with validation for ranges, lists, steps, and unsupported scheduler-specific syntax.
API & Token Tools
Parse, sort, and validate dotenv assignments while keeping the text in the browser.
Decode JWT header and payload JSON in your browser. This tool only decodes tokens and does not verify signatures.
Hashes & Checksums
Calculate SHA-256 and inspect a local file header without sending the file to a server.
Additional tools in this category
Encode text for URL components or decode percent-encoded strings in your browser for links, query parameters, and debugging.
Parse a URL into protocol, hostname, port, path, query parameters, and hash locally in your browser.

Developer & Data Tools use cases, workflow notes, and tool coverage
These eleven tools help inspect or transform structured data and development artifacts. Parser dialects, signature-verification boundaries and unsupported formats are stated on the relevant page. The Developer & Data Tools category is intended for developers, data analysts, QA teams, technical writers, and operators who need small checks while building or debugging. Each linked tool keeps the task narrow so the page can explain the input, output, and practical limits clearly.
Common tasks
- format structured data
- convert between data formats
- inspect encoded values
- test regex patterns
- prepare API or database snippets
How to choose the right tool
Use validators before trusting pasted data, converters when moving between systems, and minifiers or formatters when you need cleaner code for review.
Quality and privacy notes
Use the examples and FAQs on each tool page before relying on an output. Browser-local tools should keep input on the page, while file and web checks may depend on the browser capability described on the individual page.
