Note
If your exported source file contains data for contacts and accounts, use the Generic Map for Contact and Account data map. This is one of the default data maps provided with the Import Data Wizard.
If your source file contains records for two record types other than contacts and accounts, make a copy of the Generic Map for Contact and Account data map to customize for the records types in your source file. Import the customized data map into Microsoft Dynamics CRM, and use this data map to import your data. For more information, see Work with Data Maps.
A .zip file can include files using the .csv, .xml, or .txt formats. All files in a single compressed file must be of the same format.
You can create delimited a file in the .txt, .csv, or .xml format by using Microsoft Office Excel.
If your file uses only ASCII characters, save the file as a comma-delimited values (.csv) file.
If your file uses non-ASCII characters, save the file as a Unicode text (.txt) file.
If you want to transform data as part of the import process, identify whether the provided transformations can do the required changes. If not, decide if you need to edit your source data before importing it. For more information, see Transformation Reference.
Note
By default, the maximum size of the files that you can import is 8 megabytes (MB). This means:
The total size of the extracted files must not exceed 200 MB.
