BookYourData delivers the appended file either directly into your CRM or as a CSV or Excel file with the new columns added to your original data.
When the Data Appending service is complete, the filled fields appear as new columns alongside your existing records. You keep your original file structure and gain the missing information in the added columns.
Before committing to the full service, you have the option to run a free Data Appending test. The test fills 10 records from your file and comes back within 1 working day of the file arriving. Along with the filled records, you receive a count per field showing what was matched and filled, so you see what the output looks like before any purchase.
