Use Cases
Examples
1. Validating Payment Gateway Input
Backend Developer- Background
- A developer is building a payment gateway that requires strict adherence to ISO standards to prevent transaction errors.
- Problem
- The system needs to reject invalid currency codes provided by users before they reach the payment processor.
- How to Use
- Input the user-provided code (e.g., 'JPY') into the Currency Validator to confirm it is a recognized ISO 4217 code.
- Outcome
- The tool confirms 'JPY' is a valid code, allowing the developer to proceed with the transaction request.
2. Cleaning Financial Spreadsheets
Data Analyst- Background
- An analyst is merging multiple international sales reports into a single master file.
- Problem
- Some entries contain typos or non-standard abbreviations that break the data structure.
- How to Use
- Check each suspicious currency code against the validator to identify and correct errors.
- Outcome
- The analyst successfully identifies an invalid code 'USDT' (which is a crypto token, not a fiat currency) and corrects it to 'USD'.
