Why does my array have "extra values". How can I JSON.stringify this info?

I'm not sure if it's helpful, but you could consider converting the array into an object of some sort so that you don't lose the properties. const arr = [1, 2, 3, 4, 5, 6]; arr.low = 1; arr.high = 6; arr.median = 3; const obj = {}; for (const key in arr) { obj[key] = arr[key]; } console.log(JSON.stringify(obj)); Or you might consider grouping the array together somehow (like if you at least know none of the added properties will be numbers): const arr = [1, 2, 3, 4, 5, 6]; arr.low = 1; arr.high = 6; arr.median = 3; const obj = { arr: [] }; for (const key in arr) { // probably should be more thorough in checking if the key is an integer here... if(!isNaN(key)) { obj.arr.push(arr[key]); continue; } obj[key] = arr[key]; } console.log(JSON.stringify(obj)); More on reddit.com

How to pass JSON array as input to GitHub Actions workflow?

Not really possible. Of course you can pass a string containing JSON, but that doesn't help you run a matrix of jobs. That matrix must be statically known before the workflows are run. There may be some tricks to hack around this. For example, you could run a matrix of 10 jobs that receive the same JSON, but the nth job extracts the nth element in its steps. Or you could use the API to explicitly trigger more workflows, but the results would appear to be unconnected to the current job. More on reddit.com

streaming a large json object to a file to avoid memory allocation error

Well, JSON.stringify and JSON.parse are synchronous methods that unfortunately you can't pipe to and from. Like u/nissen2 suggests, you'll find some modules out there that will provide you what you're looking for.

Ah, I think I got it. Is there a way to permanently increase the amount of memory that node has access to? Thx.

While this may solve your problem in the mean time, I wouldn't suggest simply allocating more memory (especially with a huge JSON object.)
