CurrencySwap — RalpinMcDjango

CurrencySwap converts prices directly on the page not in a popup, not in a separate tab. Just your currency, right where the price was.

How it works

Pick your target currency, choose which ones to detect, and toggle it on. Every price on the page updates instantly. The original value stays visible in brackets so you never lose context.

CurrencySwap goes beyond basic symbol matching:

• Symbols — $, £, €, ¥, 円, ₩, ₹ and more
• ISO codes — USD, GBP, EUR, JPY and 40+ others
• Written names — yen, dollars, pounds, euros, baht, won, quid, and 70+ variations including qualified names like "japanese yen" or "swiss francs"
• Flexible spacing — handles both "20,980yen" and "20,980 yen"

Features

• Converts in-place on the page, not in a separate window
• Works alongside browser translation extensions
• Stays active as you navigate between pages
• Handles dynamically loaded content (infinite scroll, AJAX, SPAs)
• Clean restore when toggled off — no leftover markup

Privacy

• No data is collected
• No tracking.
• Nothing about you or your browsing leaves the extension.

The only network request is to ExchangeRate-API to fetch public exchange rates.
