Data Loader
Import data from CSV, XML or JSON files into your org with the Data Loader module.
¶ Uploading and mapping data
Once you have selected into which sObject you will be importing data, you are able to upload your import file. You can either drag and drop your file into the modal box or click on the Upload Files button to open an explorer window. After choosing a single file, click Save. For more information about file formats check here.
Field mapping is done instantly after uploading a file and it searches for Salesforce fields with the same name as the header / attribute. To alter mapping data, hover over the Salesforce field you wish to change and press the edit button, but make sure all the required fields are included for the specific object if inserting new records.
¶ Actions and types
The following actions are available:
- Insert - import new records, don't include standard IDs in your import file as they are automatically generated
- Upsert - import new and update existing records, an external or standard ID field can be used for matching, read more here
- Update - update existing records, standard ID is used for matching
Choosing which type of import sets certain limits in place:
- Batch - a single batch job allows a maximum of 10000 record changes
- Standard - standard operations have a limit of 200 record changes
¶ Results
While the import operation is running you are able to use other modules in Maven Tools, when the results arrive you will receive a notification in the form of a toast. Results will appear in the bottom part of the module. You can sort results by any column and there is also a search bar available in case you need to find a specific row.
If the row data is too long and isn't completely visible it is possible to hover over it and click the expand button. This will show you the full row information as well as any errors which may appear during import.
