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.

Integration

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.

Get header Set header Get property Set property Read body as String Parse body as JSON Parse body as XML Set body Log payload to MPL attachment Add custom header property (MPL search) Wrap in try/catch

Payload diff

Compare two payloads line by line - before/after a mapping, dev vs prod, you name it.

Ignore leading/trailing whitespace

Payload formatter & validator

Pretty-print, minify, and validate JSON or XML - with syntax colouring. Handy for CPI payloads and IDocs.

XPath tester

Test XPath expressions against your XML - namespace prefixes from the document work automatically.

EDIFACT segment viewer

Paste a raw EDIFACT interchange - segments get split, labelled, and readable. UNA delimiters respected.

Encoding & decoding

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.

Generators & time

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.
