Does Appian support Financial Services File Formats (BAI2)?

There's not any official or explicit Appian support for these file formats.
It's likely that an application could be designed to parse the content of the file according to the format specification.
If the files are ALWAYS reasonably short, and they're essentially text files, you could read them with the Text File Reader.

If the files are typically going to be too long to read with text file reader, you might do better to use an Appian web appian to allow the file data to be put in Appian over a web service.

Great Robert! Thanks for your suggestion. I will give it a try and confirm how it goes.
