data import wizard

Data Import Wizard—this tool, accessible through the Setup menu, lets you import data in common standard objects, such as contacts, leads, accounts, opportunities, as well as data in custom objects. It can import up to 50,000 records at a time. It provides a simple interface to specify the configuration parameters, data sources, and the field mappings that map the field names in your import file with the field names in Salesforce.

can we import opportunities using data import wizard? as i cant see any option in data import wizard... but it is clearly mentioned in trailheads of admin

You cannot import Opportunities with the built-in Data Import Wizard.  You can use Data Loader or the other collection of available tools to do that.

Hi Niranjan,

Data import wizard has some limitation bus has some benifits as well. In some cases it does not work and we have to use the Data Loader for some cases.

1) Using Data import wizard you can not import opportunity records but using data loader it possible.
2) Using data import wizard you can only import 50000 record but using data loadeer you can import upto 10million records in one go.
3) Data loader is fast in comarison to data import wizard.
4) Data import wizard prevent loading duplicate records in some case like Lead objects records, but Data loader blindly imports the records.
5) Data import wizard does not create any log for failure records but Data loader creates a log for failde records.

Hope this helps you and clears you question.....

Select this as a best answer if you thinks.
