We accept .TXT and .CSV files.
When you upload a file, be sure to select the right "File Delimiter" and to check the box, if your files contain a header row.
If you upload a multi-column CSV - You will be presented with a screen to match the columns with the data in it. We automatically detect what's in most columns and will pre-populate those columns for you.
It's important to match the column data type, because we use that information to help enhance your data. If you mark a column as "First Name" - we'll use that column to determine the gender of the Email.
If you mark a column as "IP Address" - we will use that data and tell you the location of that IP Address.
When you get your results back, you will have all your columns intact. We will append your columns to the CSV and they will be labelled as "ZB <Column Name>".
