Hey Thembelani.

You have a few options you can go for depending on what formats you are attempting to convert from.

You could look at something like using pandoc via the command line (as in, building an operation that does the command line calling, and then creating a set of request/response classes to call from a Process in your IRIS instance), or with with Python becoming more popular in IRIS, you could look what packages are available for doing what you're looking to do.

You could also look at libreoffice from the command line, but I found that headless libreoffice was a fair bit slower when running on Windows vs linux, so you may not get a lot of use with this approach depending on what you're running on.
