How can I convert nested data structures to flat ones?

How can I convert nested data structures to flat ones?

You can use various methods depending on the programming language. Are you working with JSON, XML, or something else?

I'm working with JSON data. Can you give me an example?

Sure! In Python, you can use a recursive function to flatten a nested JSON object. Would you like to see the code?

Yes, please share the code!

Here's a simple example:

def flatten_json(y):
    out = {}
    def flatten(x, name=''):
        if type(x) is dict:
            for a in x:
                flatten(x[a], name + a + '_')
        elif type(x) is list:
            i = 0
            for a in x:
                flatten(a, name + str(i) + '_')
                i += 1
        else:
            out[name[:-1]] = x
    flatten(y)
    return out

This function will convert nested JSON into a flat dictionary.
