Simplest way to work out the structure is to first export one or more records that include the data you wish to import. Once you have exported it, copy your data into the exported sheet and then go through the data import process. You map your own columns/fields however, if you have named your fields so that they can be easily identified, CRMs importer will make a good guess at what they should be mapped to. Just one word of advice I have is to make sure that when you import email addresses or addresses, set the address type.
