How to convert JSON to CSV with columns?

I'm using PHP7 and PHPExcel to import data from a third party API.

There is a JSON response that I receive. I tried to use the PHPExcel library, but I could not find anything to identify the columns in the CSV. How can I get my data into the CSV file?
This does not answer your question directly, but it is about the question: Using JSON and PHP to create CSV file. This article describes the JSON/PHP way of creating CSV files. This example uses an array in PHP which will be translated to a comma separated list of records in the CSV file.

Can you convert JSON to CSV?

You don't need special software or a whole lot of work.

The process is simple. You write a JSON to CSV converter in three steps: Write a function that converts an object (like a hash) into a string. Write a function that converts that string into the required format. Convert that function into a module that can be used by others.

There are ways to make this a bit easier to read and to keep the code compact. We'll look at those, but first, let's see what's involved.

Here's what a JSON string looks like: var json = ;. If we're interested in just the name and age properties from the above data, we'd get this: var json = ; var obj = JSON . Parse ( json ) ; var keyValuePairs = Object . Keys ( obj ) ;

We can write the key/value pairs to a CSV using some simple string manipulation, just as you would any other text file. Var keyValuePairs = Object . Keys ( obj ) ; var csv = keyValuePairs . Join ( ',' ) ; var csv = keyValuePairs . Join ( ',' ) ; var csv = `name,age` ;

The following example shows how to do this: var json = ; var keyValuePairs = Object . Keys ( json ) ; var csv = keyValuePairs . Join ( ',' ) ; var csv = keyValuePairs . Join ( ',' ) ; var csv = `name,age` ;

This results in this CSV output: But we want to include some of the properties that make up this object as well. We could extract them with a little regex, but let's stick to our format instead.
