Converting JSON to CSV: Simplifying the process of generating a table column for every field in a collection with Papa.unparse()

Using Papa Parse 4, I am encountering an issue when using Papa.unparse(collection). It appears that the resulting table is only generating columns based on the fields of the first document in my JSON collection. I would like all possible fields from my collection to be represented in the table.

For example:

{ "name": "Ross" },
{ "name": "Bob", "age": 63 }

This creates a table with just one column: "name":

name
Ross
Bob

But what I want is:

name    age
Ross   
Bob     33

Is there a way to make Papa Parse use the largest JSON object to determine the columns?

Answer №1

When using Papa parse, keep in mind that it only considers the first JSON to generate headers. To include fields from all JSON objects in your final CSV export, follow this workaround:

Papa.unparse({
    data: [ ... ],  // JSON array
    fields: [ ... ] // Fields to be added in CSV e.g. ['name', 'age']
});
