Hello All, This is my first post and would value some help please. Thanks. I want to convert this json (this is output from a parse json module) [ { “milestone-1”: “Market Analysis and Strategy Conceptualization”, “timeline-1”: “2025-08-20T00:00:00.000Z”, “milestone-2”: “Design and Development of Lead Generation Workflow”, “timeline-2”: “2025-09-05T00:00:00.000Z”, “milestone-3”: “Integration and Adaptation of [make.com](http://make.com) and airtable”, “timeline-3”: “2025-09-20T00:00:00.000Z”, “milestone-4”: “Testing, Validation, and Deployment of New Lead Generation Flow”, “timeline-4”: “2025-09-30T00:00:00.000Z” } ] I want to create this structure and have tried for hours using “Create Json” module but no luck. [ { “milestone”: “Sample Milestone 1”, “timeline”: “2025-01-01” }, { “milestone”: “Sample Milestone 2”, “timeline”: “2025-02-01” }, { “milestone”: “Sample Milestone 3”, “timeline”: “2025-03-01” }, { “milestone”: “Sample Milestone 4”, “timeline”: “2025-04-01” } ] ---

Welcome to the Make community! You can use an Iterator and an Aggregate to JSON module. From your screenshot/output bundle, it appears that you have an ARRAY of items. What do you do when you have an **array**? ## “Looping” Through Array Items When you SEE an **array** in your module’s output, think of using an **Iterator** module. In this example, responses is an array of items (collections). You’ll want to map this array in an Iterator module. ![](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/2/3/23a694ffc3939712667b383fd1b497de5d8afecb.png) ![](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/b/b/bb0162b13bbd34dbfbb41c5c399be413a9b592ec.png) **Question:** Have you tried mapping your array variable into an Iterator module, ran the scenario, and view the output? Next, ## Combining Bundles Using Aggregators Every result (item/record) from trigger/iterator/list/search/match 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](https://www.make.com/en/help/modules/aggregator.html) are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the [**Array aggregator**](https://www.make.com/en/help/tools/flow-control.html#array-aggregator) module. The next popular aggregator is the [**Text Aggregator**](https://www.make.com/en/help/tools/tools.html#text-aggregator) which is very flexible and can apply to many use-cases like building of JSON, CSV, HTML. You can find out more about the other types of aggregator modules here: - [Array aggregator](https://www.make.com/en/help/tools/flow-control.html#array-aggregator) - [Text aggregator](https://www.make.com/en/help/tools/tools.html#text-aggregator) - [Numeric aggregator](https://www.make.com/en/help/tools/tools.html#numeric-aggregator) - [Table aggregator](https://www.make.com/en/help/tools/tools.html#table-aggregator) - [JSON aggregator](https://www.make.com/en/help/tools/json.html#aggregate-to-json) - [CSV aggregator](https://www.make.com/en/help/apps/file-and-document-management/csv.html#create-csv) - [Archive (ZIP) aggregator](https://www.make.com/en/help/apps/built-in-apps/archive.html#create-an-archive-973677) - _other app-specific aggregators_ **Question:** Which is the best aggregator do you think you’ll need for your use-case? ## Example Here is an example of how your scenario could look like: [![](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/6/d/6d9029f238d0e4e1f6da77dca8ba425d5739aac9.png)](https://samliew.com/make-expert?Referrer=Make) This is just an example. Your final solution may or may not look like this depending on your requirements and actual data. For more information, see “[Mapping with arrays](https://help.make.com/mapping-arrays)” in the Help Centre. You should also do the [Make Academy](https://academy.make.com), which also covers the use of [Iterators & Aggregators](https://academy.make.com/courses/IntermediateC01). Hope this helps! Let me know if there are any further questions or issues. P.S.: investing some effort into the tutorials in the [Make Academy](https://academy.make.com) will save you lots of time and frustration using Make! — @samliew ---

Thank you for the detailed information. I really appreciate it. I did not try the iterator first as I thought I could use the “Create Json” to achieve my objective. I will definitely review in more detail and aim to get some more education and practice under my proverbial belt! 🙂 ---
