It sounds like NationBuilder will help you import data! Because data will be created and/or merged into your nation, its important that the data is imported precisely. Therefore, we ask that you please provide NationBuilder with the following.

1) A spreadsheet of the people, finance or membership data (CSV format is preferred).

2) A key or explanation of your column mappings. Your column mappings are also known as the headers of your spreadsheet. This is necessary so that NationBuilder support can map your data into the nation. For more resources on what your headers align to see: 

http://nationbuilder.com/fields_available_for_import

If you will not require particular columns, please indicate that as well.

3) A unique identifier. A unique identifier (ID) is data that exists in only one profile within a nation. Think of it like a social security number: a particular value can only exist in that field in one record in your database. Unique IDs are used to merge information from imports with existing records in your nation. All imports must include a unique ID, see:

4) Specify whether the import will be supporters or prospects, see:

Once we receive this information from you, NationBuilder can reply with an estimate for completion time. Please note that this service is complementary during your free trial, but it might quoted as a paid service depending on the complexity of your data. If you are outside of your trial period, please contact [email protected] to see if you are eligible for an import as a paid service.
