Exporting the feature class to CSV Format

Exporting Geodatabase toComma Separated Value Format

Let start creating an python addin for converting the feature class in your geodatabase to CSV format.So that everyone can understand your feature class and its values.

• If you are very new to python addin then go through- How to start with python addin 
• The input feature class and output csv file path are hard coded in the sample program
• For dynamic conversion get the path of the files through a variable and pass it as a parameter to the defined functions
