What is the best way to operate on JSON - pulling, adding and doing a trigger?

[momorix]

Ladies and gentlemen ,i learn by doing simple examples but every time when try to extract some data yourself, rework it and display it as I want it, I have a problem.

I never know when and how and what I have to use to get a typical json

[
    { item1:
     [ '1',
       '2nd',
       '3thv'
    ] },
    { item2:
     [ '1',
       '2nd',
       '3th'
     ] }  
]

I'd like to format it so that I can delete it into a csv file


My second question is how the easiest way to trigger an event

For example. Gets a get to the json with the X:Y data, then i want the Y value to run a function that returns the new get to another enpoint with a value that depends on X

There really is no such thing as a typical JSON.
The JSON file syntax allows for a wide range of valid files, some of which are 'legal' but poorly constructed. This can make handling certain JSON files quite tricky

I can't provide links here but the following may be helpful
1. There are free online converters that allow you to convert e.g USON to CSV
2. I have an app on my website which is used for analysing the structure of JSON files then transforming the file for importing into Access as one or more normalised tables.
3. Excel has a very powerful built in feature originally called Power Query but now Get & Transform. This does the same as my Access app but the feature isn't available in Access unfortunately.

Suggest you do an online search for each of these or send me an PM if you need more info.

I have no experience of working with JSON using JavaScript

Sorry but I have no idea what your second question means

Make changes in the code to parse the obtained json correctly. Once that is achieved, conversion to csv can be done.

but how am I supposed to parse it ?

Did you investigate any of the three suggestions I made?
You can also find JSON parsing code on e.g. GitHub

but how am I supposed to parse it ?

By writing some code. What is the progress so far?
