The Ultimate Step-by-Step Guide to Building a No-Code Real-Time Currency Converter
Introduction: Why Build a Currency Converter Without Code?
In today’s fast-paced digital economy, currency conversion is an essential feature for businesses, travelers, and finance professionals. The good news? You don’t need to be a developer or write a single line of code to build a fully functional real-time currency converter.
Thanks to powerful no-code platforms, you can create a seamless, automated, and professional-grade currency converter that updates in real-time. This guide will take you from zero to hero, covering every essential step in an easy-to-follow format.
Step 1: Choose the Right No-Code Tools for the Job
To build a robust real-time currency converter, we’ll need a no-code app builder, a data source, and an automation tool to fetch live exchange rates. Here’s the perfect tech stack:
-
Bubble.io – No-code platform for building the user interface.
-
Google Sheets – Database for storing live exchange rates.
-
Zapier – Automates fetching the latest currency rates.
-
ExchangeRate-API – A reliable currency data provider.
With this setup, your currency converter will be lightning-fast, fully automated, and completely scalable.
Step 2: Set Up Google Sheets to Store Currency Exchange Rates
1. Create Your Google Sheet
-
Open Google Sheets and create a new sheet named "Currency Data".
-
Set up the following columns:
-
Column A:
Currency Code
(e.g., USD, EUR, GBP) -
Column B:
Exchange Rate (to USD)
-
Column C:
Last Updated
-
2. Fetch Real-Time Exchange Rates
-
Sign up for a free API key at ExchangeRate-API.
-
Copy your API Key.
-
In Google Sheets, enter this formula in cell B2:
=IMPORTDATA("https://v6.exchangerate-api.com/v6/YOUR_API_KEY/latest/USD")
-
This formula pulls live currency exchange rates and updates them dynamically.
Pro Tip: If you want multi-currency support, repeat this process for different base currencies (EUR, GBP, etc.).
Step 3: Automate Currency Rate Updates with Zapier
Keeping exchange rates up-to-date automatically is crucial. Zapier can refresh your data every hour without any manual effort.
1. Configure Zapier Automation
-
Sign up on Zapier (zapier.com).
-
Click "Create a Zap".
-
Choose "Schedule by Zapier" as the trigger.
-
Set it to run hourly (or daily for lower API usage).
-
-
Select Google Sheets as the action.
-
Choose "Update Row".
-
Connect your Google Sheets account.
-
Pull live rates from ExchangeRate-API.
-
-
Test & Activate – Your Google Sheets now auto-updates without lifting a finger!
Pro Tip: Use Make (Integromat) as an alternative to Zapier for more control over automation.
Step 4: Build the Currency Converter in Bubble.io
1. Set Up Your No-Code App
-
Sign up at Bubble.io.
-
Create a new app.
-
Go to Data → Add a new Data Type named Currencies with fields:
-
Currency Code
(Text) -
Exchange Rate
(Number)
-
-
Install the Google Sheets Plugin to pull live rates from your sheet.
2. Design the User Interface
-
Open the Bubble Editor and go to the Design Tab.
-
Drag & drop the following elements:
-
Input Field → User enters an amount.
-
Dropdown #1 → Select the currency to convert from.
-
Dropdown #2 → Select the currency to convert to.
-
Button → "Convert" action.
-
Text Box → Displays the converted amount.
-
Pro Tip: Enhance UX with auto-detect currency based on the user’s location.
Step 5: Add Conversion Logic & API Integration
1. Create the Conversion Workflow
-
Go to Workflows in Bubble.
-
Set up an event: When "Convert" Button is Clicked → Perform actions:
-
Get input amount.
-
Fetch exchange rate from Google Sheets.
-
Multiply Amount × Exchange Rate.
-
Display the converted amount.
-
2. Optional: Use Direct API Calls
For even faster conversions, pull rates directly from ExchangeRate-API:
-
Install Bubble API Connector.
-
Configure an API call to
https://v6.exchangerate-api.com/v6/YOUR_API_KEY/latest/USD
. -
Fetch live rates and display conversion instantly.
Step 6: Test, Optimize & Deploy
-
Click "Preview" in Bubble to test the currency converter.
-
Check for accuracy in conversions.
-
Optimize the UI with colors, fonts, and animations.
-
Deploy your app and share the public link!
Pro Tip: Use Adalo to convert this into a mobile app for iOS/Android.
