Excel 2013 error; [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Based on your description, your Windows system is 64-bit and your Office is 32-bit.

I suggest you refer to this support article first:
https://msdn.microsoft.com/en-us/library/ms712362(v=vs.85).aspx

As the article said: To manage a data source that connects to a 32-bit driver under 64-bit platform, use :\windows\sysWOW64\odbcad32.exe.
To manage a data source that connects to a 64-bit driver, use :\windows\system32\odbcad32.exe.

Make sure that you create your ODBC link using the 32 bits ODBC Manager: C:\Windows\SysWOW64\odbcad32.exe
