powerpoint - iterate to a group of slides

Hi Everyone, 

I'm trying to generate a .pptx from some dataverse data. The template will have 3 static slides (intro, data, data with a table repeater), and a group of slides for each component I'm pulling from a list. 

I'm not clear on how to define a repeater for a slide that contains a table and multiple additional slides.

{    
    "title": "example JSON",
    "elements": [
        {
            "images": ["encode64","encode64","encode64"],
            "name": "first",
            "tables": [{"name": "1"},{"name": "2"},{"name": "3"}]
        },
        {
            "images": ["encode64","encode64","encode64"],
            "name": "second",
            "tables": [{"name": "5"},{"name": "6"},{"name": "7"}]
        }
    ]
}

I would like to get out of this 3 initial slides based on "title" than a slides for each "elements", a slide for each image, so in this example will be 4 slide per element, one for the element and 3 for the images.

Reading the documentation  seems i would be able to repeat a slide or repeat a table and not both at the same time. 

Expectation:

Slide1 Slide2 Slide3 (static) -> Slide4(first and containing a table with values 1,2,3) -> Slide5 Slide6  Slide7(each containing one of the images in the array) -> Slide8(repeat of Slide4 and containing a table with values  5,6,7) ->Slide9 Slide10  Slide11(each containing one of the images in the array).

Will I be able to achieve this?

    I managed to get around it i can use more complex flows to generate only the slides I need then concatenate them in a bigger document.

    Hello,

    Glad to hear you managed to resolve this - For the benefit of anyone else that may ask the same question in the future, I am in the process of putting something together and doing some testing. Will share this here when I have more information on this for you.

    Hi Kayleigh, 

    I pretty much broke down the presentation in more editable bits, instead of passing a giant JSON and have sections to repeat, i render the presentation in blocks, i render slide 1,2,3 in the first part and write the file in OneDrive, I then render slide 4 and write it OneDrive, then i render slide 5,6,7 and write on one drive and i repeat for slide 8, then for 9,10 and 11. Once i have all the pieces together i merge them in a big presentation. The template for 4 and 8 is the same and the same is the one used for 5,6,7,9,10,11 that uses a compose with the property new slides set to "yes".

    Hi Mauro,

    I believe you have taken the correct approach by dividing the presentation into segments and then merging everything together at the end. I have focused primarily on the tables and images within your request, as the first three slides—containing only the <<[title]>> tag—are relatively straightforward when using JSON input.

    I have configured two Populate PowerPoint actions: one for tables and one for images. Both actions have “Multiple Slides” enabled.

    Tables

    The first action (for tables) uses the JSON shown below.

    [{
    "name" : "first",
    "tables": [{ "name": "1" }, { "name": "2" }, { "name": "3" }]
    },
    {
    "name" : "second",
    "tables": [{ "name": "5" }, { "name": "6" }, { "name": "7" }]
    }]

    The corresponding template contains a single slide with a table and the following syntax, along with a <<[name]>> tag positioned above the table:
    <<foreach [t in tables]>><<[t.name]>><</foreach>>

    Images

    The second action (for images) uses the JSON displayed below.

    [
    {"images" : "base64"},
    {"images" : "base64"},
    {"images" : "base64}"}
    ]

    The associated template is also a single slide and contains the following tag:
    <<image [images] -keepRatio>>

    I used a Merge action and then configured the action to reflect the order of slides that I wanted to achieve the below. As you can see, the slides containing the three individual images appear between the slides generated for the tables.
