ASN1 to CSV Translator

ASN2CSV (ASN.1 to CSV translator) is a command-line tool for translating data encoded using BER, DER, or CER ASN.1 encoding rules to CSV format.

It provides the capability to transform ASN.1-encoded data to a delimited format by assigning an ASN.1 schema to binary data. No programming is required to produce the output, and the conversions may be done in a batch process.

ASN2CSV is envisioned primarily as a tool in a workflow that helps transform call data records (CDRs) into formats usable by other tools like databases. It is optimized for this purpose, since hierarchical data like BER is difficult to transform into a flat format like CSV.

As an example, the following command-line can be used to translate a Tranferred Account Procedure (TAP3) batch file to CSV format:

asn2csv message.dat -schema TAP-0311.asn

The resulting output would be as follows:
