Iterator and aggregator

[Thomas_Koch_Nielsen]

OK… I give up…
Why does this add 4 rows to my google sheets when Im only iterator 2 bundles?

Hey @Thomas_Koch_Nielsen Blueprint doesn’t help to understand the number of operations well. Could you please share the screenshot after running your automation??? That would help to identify the issue. And also please share the screenshot of output from iterator.

This is because your Google Sheets search module is returning two results (bundles) per operation.

You need to limit to one result, otherwise you need to aggregate the results (if you are expecting more than one result).

Aggregators

Every result (item/record) from iterator/list/search modules will output a bundle. This can result in multiple bundles, which then trigger multiple operations in future modules (one operation per bundle). To “combine” multiple bundles into a single variable, you’ll need to use an aggregator of some sort.

Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module. The next popular aggregator is the Text Aggregator which is very flexible and can apply to many use-cases like building of JSON, CSV, HTML.

There are other types of aggregator modules, click the below links to find out more:

• Array aggregator
• Text aggregator
• Numeric aggregator
• Table aggregator
• JSON aggregator
• CSV aggregator
• Archive (ZIP) aggregator
• other app-specific aggregators

Array Aggregator – mapping multiple bundles into a complex field

The Array Aggregator module is very powerful because it allows you to build a complex array of collections for a later module’s field to map multiple items (collections) to it.

This is done using the “Target structure type” of an Array Aggregator module.

Here is an example:

As you can see, the “Map” toggle on complex fields are used when you have an array. You can easily build an array variable to map to a future module’s field, by using an Array Aggregator module and select the “Target Structure Type” as the future module’s field you have mapped the array into.

Hope this helps! Let me know if there are any further questions or issues.
