Tools
Handy dev tools 🛠️
Small utilities I keep needing - so I put them here. Everything runs in your browser; nothing you paste ever leaves this page.
CPI Groovy snippet builder
Assembles a ready-to-paste script for SAP Cloud Integration. Targets the current
Groovy 4 runtime - including the groovy.xml import that the
XmlSlurper now needs.
Payload diff
Compare two payloads line by line - before/after a mapping, dev vs prod, you name it.
JSON formatter & validator
Pretty-print, minify, and catch syntax errors.
XML formatter
Pretty-print with syntax colouring - handy for CPI payloads and IDocs.
Base64 encode / decode
UTF-8 safe - handles special characters correctly.
URL encode / decode
Percent-encoding for query parameters and endpoints.
JWT decoder
Decodes header and payload locally. Signature is not verified - this only reads the token.
UUID generator
Version 4, cryptographically random.
Cron expression explainer
Standard 5-field cron: minute, hour, day of month, month, day of week.
Epoch timestamp converter
Seconds or milliseconds - auto-detected.
