Pop-up Currency Converter par VEKU DAZO

Currency Converter
Yeah it converts currencies. Select text on a price, see what it is in your money through a magical POP-UP. You're welcome.

Rates from frankfurter.app. Cached 5 minutes because the API doesn't need to know every time you input something.



Converter

• Select any price text on a page. Popup appears. It converts.
• Both boxes are editable. Change either one, the other follows. Bidirectional, very fancy.
• Two ⇅ buttons. One swaps the amounts, one swaps the currencies. They do different things, I know it's confusing, there are tooltips.
• Pin up to 3 currencies if you're tired of finding them in the dropdown every time.
• $ and ¥ mean different things in different countries, surprisingly. It guesses which one based on the site's TLD, language, and some meta tags. You can correct it and it'll remember per domain.
• Right-click on any page→ Load Converter UI if you just want to open it without selecting anything.

Dumb shopping site wont let you select the text on the price?
Make use of -
Scanner

• Scans the page and dumps every price it found into a list.
• Click one to input into Converter. Hover to see where it lives on the page.
• Draw a box if you only care about part of the page.
• Handles prices that are split across multiple elements because apparently that's a thing websites do.

Gotta say

• Validates against 31 ISO 4217 codes from api.frankfurter.app. Needs at least one digit, 2–60 chars, ignores whatever garbage is in your selection. Understands k, million, billion because some sites think that's helpful.
• DOM is a mess everywhere, so it stitches split prices back together, guesses ambiguous symbols, and keeps working offline with stale rates when the API decides to take a break.
• Update me on sites where it doesn't work like we would like it to, that's helpful.
