All the tools you need,in one place.

What you can do here

Utilerio is a focused collection of utilities for four jobs that keep coming up in day-to-day work: reading and fixing structured data, producing barcodes and labels, moving files between formats, and doing the commercial arithmetic behind an online order.

The barcode and label section covers Zebra's ZPL language end to end. You can paste ZPL and see the rendered label, export the same code as a print-ready PDF, or save it as a PNG for a ticket or a supplier email. Alongside that sit a barcode generator with per-symbology validation and a QR code generator that handles Wi-Fi credentials and contact links, not just plain text.

The developer and file-conversion sections handle JSON, XML and CSV. Formatting, validation and conversion all happen inside the browser tab, which means a production payload you are debugging never leaves your machine. Errors are reported with the line and column where the parser gave up, so you can fix the document instead of guessing.

The calculators cover the numbers behind selling something: VAT in both directions, single and stacked discounts, the difference between margin and markup, volumetric shipping weight, and what is actually left after a marketplace takes its commission.
