How do I convert a SWIFT message to JSON using LetsConvert?

Upload your .swift file (MT or MX messages) via the upload area. Choose JSON as the output format. Click 'Convert' and wait for the transformation to complete. The JSON file will be available for download, with SWIFT tags mapped to JSON object keys.

Why should I convert SWIFT to JSON instead of using the native format?

SWIFT messages are designed for banking network communication, while JSON is a lightweight data format universally supported by web apps, APIs, and databases. Converting to JSON makes financial data easier to parse, analyze, and integrate into modern systems like dashboards or payment platforms, without losing critical transaction fields.

What happens to SWIFT field tags and transaction metadata during conversion to JSON?

Each SWIFT field tag (like :32A: for currency and amount) becomes a key in the JSON object, and its value is preserved exactly as in the original. Sub-fields, optional blocks, and message metadata (e.g., sender/receiver BICs) are retained in a nested JSON structure. No data loss occurs; the conversion is lossless.

Is SWIFT-TO-JSON free to use?

Yes, SWIFT-TO-JSON on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! SWIFT-TO-JSON works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
