This is the Firefly III CSV importer documentation. Welcome!
The Firefly III CSV Importer is a tool that you can use you import data from CSV files into Firefly III. It has several interesting features, and it can be used to import data manually, semi-automated or entirely automated.
Firefly III used to have a CSV importer built right in. However, it turned out that this is impossible to maintain and prone to errors. It's a lot cleaner to use a separate tool, and easier too.
You can install the CSV importer either self hosted, through Docker variant, or by using the online variant. Keep in mind that the online variant is hosted by yours truly and doesn't guarantee the privacy or safety of the documents you upload.
