How to Use Make.com's Array Aggregator to Filter and Organize Data
Struggling to extract specific information from multiple data records? The Array Aggregator in Make.com lets you filter and reorganize data exactly how you need it. Perfect for event planning, customer data processing, and any scenario where you need to focus on specific details from multiple sources.
Understanding Array Aggregators
Most business owners dealing with multiple data records face the same challenge: how to extract and organize only the specific information they need from each record. Make.com's Array Aggregator solves this by letting you combine multiple bundles of data while filtering for only the fields you want.
Think of it like cooking soup from many ingredients - you don't throw everything in the pot, just select what you need. The Array Aggregator works similarly, letting you pick specific data "ingredients" from each bundle to create a new, organized array.
Key difference: While text aggregators combine data into simple strings, array aggregators maintain the structured nature of your data, making it easier to use in subsequent steps of your automation.
Real-World Use Case: Party Planning
Imagine planning an event where you need to know attendees' dietary preferences to order food. You receive multiple responses (bundles), each containing various information - names, contact details, plus ones, and dietary needs. The Array Aggregator lets you extract just the names and dietary preferences, filtering out everything else.
In our tutorial scenario, we worked with three party invitation responses (three bundles). Using the Array Aggregator, we created a new array containing only names and dietary preferences - essentially a shopping list for our event catering.
Practical application: This same technique works for processing survey responses, organizing customer data, compiling reports - any situation where you need to extract specific information from multiple records.
Setting Up the Scenario
The foundation of our array aggregation starts with properly structured data. We began by creating a new scenario named "Make Intermediate 1-3" and added a Parse JSON module containing our guest information in proper JSON format.
This JSON structure included an array with three collections (guest responses), each containing properties like name, email, and dietary preference. The Parse JSON module converted this into a single bundle that our iterator could process.
Pro tip: Right-click the Parse JSON module and select "Run this module only" to verify your data structure before proceeding with the rest of the scenario setup.
Working With Iterators
Iterators are crucial when working with array aggregators. They take our single bundle (containing multiple records) and split it into separate bundles - one for each record. In our example, the iterator converted our one bundle with three guest collections into three separate bundles.
We then added a filter between the iterator and router to only pass through bundles where dietary preference wasn't "none." This reduced our three bundles to two that actually contained dietary restrictions we needed to accommodate.
Important note: Filters are case-sensitive - "none" (lowercase) didn't filter out "None" (capitalized). Always verify your filter conditions match your data format exactly.
Adding the Array Aggregator
The array aggregator was placed on the top route after our router. Under source module, we selected the iterator (not the Parse JSON module) since we wanted to aggregate the iterated bundles. In the aggregated fields, we selected only "name" and "dietary preference" - the specific information we needed for our shopping list.
This created a new array containing just these two properties from each bundle that passed through our filter. The result was a clean, organized data structure containing only the information we needed for our event planning.
Comparison point: On the bottom route, we used a text aggregator to create a simple string output of the same information, demonstrating how array aggregators maintain structured data while text aggregators create flat outputs.
Comparing Aggregator Types
While both array and text aggregators achieved our goal of compiling guest dietary information, their outputs serve different purposes. The text aggregator created a simple string that might be sent as an email or message, while the array aggregator maintained structured data that could be processed further.
Array aggregators shine when you need to: map data to other applications that expect array inputs, perform additional processing on the organized data, or maintain the relationship between different properties (like which dietary preference belongs to which guest).
Decision guide: Use text aggregators for final human-readable outputs. Use array aggregators when you need structured data for further processing in your scenario.
Common Pitfalls and Solutions
One common issue is filter conditions not matching data formats exactly, as we saw with the "none" vs "None" example. Always check your filter results carefully and consider using text formatters to standardize case before filtering.
Another potential problem is selecting the wrong source module. Remember to choose the iterator (not the original data source) when setting up your array aggregator, since you want to aggregate the iterated bundles, not the original collection.
Troubleshooting tip: Use Make.com's "Explain Flow" feature to visualize how your data moves through the scenario and verify it's being processed as expected at each step.

Key Takeaways
Make.com's Array Aggregator is a powerful tool for extracting and reorganizing specific data from multiple bundles. Unlike simpler aggregators, it maintains the structured nature of your data, making it ideal for scenarios where you need to process information further before final output.
In summary: Array aggregators let you create new, focused arrays from multiple bundles while filters help you include only the records you need. This combination is perfect for event planning, survey processing, and any data organization task where specificity matters.
Frequently Asked Questions
Common questions about this topic
An array aggregator in Make.com is a tool that combines multiple bundles of data into a single array. It allows you to extract specific pieces of information from each bundle and organize them into a new structured format.
Unlike text aggregators that create simple strings, array aggregators maintain the structured nature of the data, making it easier to use in subsequent modules of your automation scenario.
- Combines multiple bundles into one structured array
- Lets you select specific fields from each bundle
- Maintains data structure for further processing
Use an array aggregator when you need to maintain structured data for further processing in your scenario. Use a text aggregator when you simply need to combine information into a readable string format for output.
Array aggregators are particularly valuable when the aggregated data needs to be mapped to other applications or processed through additional modules in your workflow.
- Arrays: For structured data needing further processing
- Text: For final human-readable outputs
- Arrays maintain field relationships; text combines everything
Filters can be placed before array aggregators to control which bundles get included in the final array. They use conditional logic to evaluate each bundle and determine whether it should continue through the workflow.
In our tutorial example, we filtered out guests with 'none' as their dietary preference, ensuring our final array only contained guests with actual dietary restrictions we needed to accommodate.
- Filters evaluate each bundle before aggregation
- Conditions must match data format exactly
- Help focus your array on only relevant data
Yes, you can use multiple array aggregators in a single scenario, each creating different arrays from the same or different sets of bundles. This is useful when you need to organize data in multiple ways for different purposes.
For example, you might create one array of customer names and contact information for a mailing list, while simultaneously creating another array of their purchase history for reporting purposes.
- Multiple aggregators allow different data organizations
- Each can focus on different fields from the same source
- Helpful for creating parallel data processing paths
Array aggregators are incredibly versatile for business automation. Beyond our party guest example, they're excellent for processing survey responses, organizing customer data, compiling reports from multiple sources, and any situation where you need to extract specific information from multiple records.
They're particularly valuable when you need structured output for applications that expect array inputs, like certain email marketing platforms or CRM systems.
- Event planning and guest management
- Survey and form response processing
- Customer data organization and segmentation
Array aggregators themselves don't consume additional credits - the credit consumption comes from running the scenario that contains them. The iterator that creates the bundles does consume credits, but the aggregation process afterward doesn't add extra costs.
This makes array aggregators a cost-effective way to organize your data, as you're only paying for the initial processing of records, not for the subsequent organization and filtering.
- Aggregators don't add to credit consumption
- Iterators are what consume credits
- Filters and routers also don't use extra credits
Filter conditions in Make.com are case-sensitive and must match exactly. In our tutorial, we saw that 'none' (lowercase) wouldn't filter out 'None' (capitalized) because the conditions are evaluated precisely.
It's crucial to know your data format and test your filters thoroughly. Using text formatters to standardize case before filtering can help avoid these issues and ensure your filters work as intended.
- Conditions are case-sensitive
- Must match data format exactly
- Text formatting before filtering helps ensure matches
