Autoloader File Preparation

Jump to: navigation, search

This section of the Autoloader settings page allows for manipulation of the data prior to the Autoloader actually loading the data onto the system.

Use Cases

  • Using Merge Control, you can merge two or more columns in your csv upload file so that their data is loaded into one SmartSimple field.
  • Using Constant, you can set a constant value to be uploaded to a specific field for all records. You can also use this feature with an autonumber field to add sequential autonumbers to added or updated records.

Merge Control

Example: For an autoloader with four columns, where the first column updates and matches by the Owner standard field, the format of the uploaded file must be firstname [space] lastname. However, the csv file being used for the upload contains two columns, one containing the first name and one containing the last.

It is a trivial matter to concatenate these two columns in Excel or other spreadsheet programs; however, the conversion process from Excel back to csv may introduce errors into the upload file. As well, if the file is uploaded to the SmartFolder automatically to trigger the autoloader process, there will not be an opportunity for this intervention.

The solution is to use Merge Control to concatenate the first name and last name into one column. In this example, we've entered 1= ,2,3. This means that the first column will be replaced by the value of columns 2 and 3, separated by a space.

Syntax

[column number to be replaced]=[separator],[column 1],[column 2],...,[column n]

Multiple Merge Controls can be used in the same autoloader, separated by double semicolons. Example: 1= 2,3;;20=|,4,5,6

Constant

An Autoloader Constant can be defined to update your autoloaded records to a single, constant value. As above, it is straightforward to create a single upload file with the same value in each row for a column. But when dealing with multiple uploads that do not already contain a constant value, or automatically-uploaded files, using the Autoloader Constant is the recommended method.

Syntax

[column number to be replaced]=constant value or [column number to be replaced]=~ (for autonumber increments)
Multiple Merge Controls can be used in the same autoloader, separated by double semicolons. Example: 2=~;;4=12345

Constant value

To populate your uploaded records with a constant value, simply indicate the column number of the destination field followed by the equals sign and your constant value. Example is to populate the Status of imported users to "Inactive" with statusid=12345. In the File Layout tab, map item 4 for * Status ID and in the  Process tab under the File Pre-Processing section add in the Constant textbox: 4=12345.

Autonumber

The Autoloader Constant can also be used to increment an autonumber field for each uploaded record. For example, if the second column mapping in your autoloader has an autonumber field selected as its destination, enter 2=~ into the Constant section of the Autoloader settings.

Current Date

  • Available after November 2019 upgrade.

To populate your uploaded records with the current date, simply indicate the column number of the destination field followed by the equals sign and the current date: now(). Example: 5=now().

Resulting Files

When a Merge Control or Constant is defined, once the import file is uploaded to a SmartFolder, the file will be altered according to the rules established in the Merge Control or Constant settings and a new upload file will be created with the prefix "mod_".

Both the original upload file and the file modified by the Autoloader File Preparation processes will be available for review in the SmartFolder.
