Correct file format
If you are having trouble importing your CSV into Jumplead it could be that your file is actually tab separated rather than comma separated as a CSV (Comma Separated Values) should be.
When exporting your CSV from your spreadsheet program ensure that the delimited/separator is set to "," (the comma character).
Here is an example of a correct CSV file:
First Name,Last Name,Email Address,Company
Here is an example of an incorrect tab delimited file:
"First Name" "Last Name" "Email Address" "Company"
"Tony" "Stark" "email@example.com" "Stark Industries"
"Peter" "Parker" "firstname.lastname@example.org" "The Avengers"
"Bruce" "Banner" "email@example.com" "The Avengers"
"Hank" "Pym" "firstname.lastname@example.org" "X-CON"
If you find after importing that some of your contacts are missing, double check that they have both a name and an email address. As these fields are both required to create an contact and if they are not both present the record is skipped.
