From the creator of the Paint color finder and estimator, I created a spreadsheet that uses the global price data from the Blockmarket website to tell you which crafting recipes are the most profitable.
A quick guide to how to use the spreadsheet is included. Currently, the spreadsheet is on both Google Sheets and in Excel. The Google Drive version is public, but editing is restricted to settings, as everything else updates automatically. With the Excel version, you can do whatever you want with it.
The spreadsheets will be updated periodically. You can make sure you have the current version by looking at the bottom-right corner of the how-to page. The current version number is 0.1.6.
