Hi there 

Thank you for posting in the Community! Unfortunately automatically converting a Salesforce process builder is not currently supported in Lucidchart. However we're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our feature request form? Ideas submitted to this form are passed on to the product development team for their consideration.

Apologies for the inconvenience - please let us know if you have any additional questions!
