This program will connect to your mysql database and convert all items into a csv file which you can convert back into a DBC file.
This will only work for Windows and Trinitycore 3.3.5 or as long as the tables required column names are the same as TC.

This is also created using Windows Frame App (.NET framework) so this will only work for windows OS. I'd recommend reading readme.txt file as well.

Step 1: Fill in Mysql Database Connection Information and hit connect.
Step 2: Click create patch.
Step 3: Convert the Item.dbc.csv file that was created by dragging and dropping it on to DBCutil.
Step 4: Place in your servers DBC Folder and add to your patch.mpq.
Step 5: Enjoy!
