I have the below values and I want to create a macro to add the duplicates and delete it.

Apple=260
Orange=3
Banana=246
Apple=43
Mango=93
Banana=4
Melon=260
Grape=209

After I run the macro, i want the result to be in the same column with the data as below

Apple=303
Orange=3
Banana=250
Mango=93
Melon=260
Grape=209

Please help me on how to do it. Thanks in advance!
