To help with this, I created a quick simple script that will generate a table with all your sales (item name, ID, sales price, etc) in an Excel-pastable format. If you sell on Mercari, you may want to try it out if you are filing taxes.
Notes: I quickly whipped this up, it's not pretty but it does the job (for me at least). I'll clean it up and make it more useful (date searching, and some other features) when I have time. Also, will post to my GitHub to track it, but for now will just dump the code. This will probably work in Firefox as well, but only tested in Chrome.
Steps
- Go to your sold items page (出品した商品)
- In the browser, open up the developer tools
- Click the console tab if it's not already open. If there are errors and warnings here, you can ignore them
- Paste the code below and hit "Enter"
- Open up Excel and "paste"
Code: Select all
