A free mod for Mount & Blade II: Bannerlord, by Doc_Monster7.

This is a simple mod to generate a JSON file of all the transactions that have taken place in-game. There are many types of transactions, which can range from buying and selling items to recruiting troops, purchasing workshops, etc.

How does it work?

After Loading a save game or Starting a new campaign, this mod will create an Account .json file in your game directory through which you can convert JSON files to EXCEL or any other desired format.

Note:

The JSON file is generated in a different way than how the game is played. It is generated in the form of a list and it is not limited to only the transactions related to buying or selling items.
