MT103 Parser / Viewer
Turn an MT103 text message into readable fields while retaining the original source.
Inputs and files stay in this browser tab. These tools do not upload, log or save your data. Clear the workspace when finished.
How to use MT103 Parser / Viewer
Paste one message or upload a TXT file, then select Parse MT103. Review blocks and tagged fields. Open Raw message to compare the source. Body-only tagged text is accepted with warnings for missing common fields.
Limits and interpretation
Text-structure parsing does not authenticate a message, confirm SWIFT delivery or prove settlement. No full FIN validation is performed. One message at a time; tags must start on separate lines. Dates retain their two-digit year without guessing a century. Unrecognized values remain raw.
Is my input sent to a server?
No. Parsing, filtering and validation run locally. Only an explicit copy or download action exports your results. Closing this page clears its working input.
