TLV Parser is useful for parsing Tag Length Value (Data).
To use the app, simply paste or type an hexadecimal string of TLV data into the input field in the home screen of the application and then press the Parse Tlv button. If the data is valid, it gets parsed and displayed in a list on the home screen. If some parts of the data are not valid, it parses and display up to the TLV value before the invalid one and displays an error message explaining what the issue is.
