Very chaotic excel form, ask for guidance to sort out, finally want to become SQL or js mongodb

  mongodb, question

Ask the Great God to guide how to sort out such a mess of data. The first group is in November and then the next group is in December. But they are in a sheet. . . I tried to use tableau to organize and failed. . .
This data format is quite complete, so I want to make a database. But it’s really too messy to know what to do, ask the great god for help! ! ! Thank you! ! !

Read out the code and insert it directly into the database
Read out a line is an array, as long as there is a regular code can be written
