I recently started using "go" for a project and found it to be a great choice. Initially as a learning tool, I created a simple application to convert csv files to beancount journal format, after preprocessing them using google sheets. I thought I'd share it with the group. Here's the link to the repository on Github: https://github.com/PaulsTek/csv2bean
It's been helpful for me in dealing with csv files and I hope it can help someone else too. Let me know if you have any questions or feedback.
