Show HN: Datamorph – A clean JSON ⇄ CSV converter with auto-detect

  Tried it on a 9.9MB json file I have. Seemed to handle the size fine, but the output was nothing like what I would want. I made a smaller version of what I uploaded in the below pastebin and the output.

  The data is TLD data so it should have at least given me the "com", "net", "..." part

  Input

  https://pastebin.com/QAWeu8Xt

  Output

      category,addedToListPrice,appliesToCustomers,amountRateType,amountRate,type
      fee_tax,false,eu,percent-varies-by-location,~,vat
      fee_tax,false,in,percent,15,gst
      fee_tax,false,au,percent,10,gst
      fee_tax,false,eu,percent-varies-by-location,~,vat
  

  An explanation of _how_ it does the conversion would be nice when choosing a tool like this. As the "just works" didn't seem to work.

    Sorry for this incorrect output. Earlier my code wasn't compatible with deep nested Json. Thanks for pointing that out and now I have successfully modified codebase to support the similar JSONs. You can try it out!!

    Please feel free to report any more obstacle in app experience.

    I love the smell of vibe coding in the morning.

      No engagement from the OP. I guess they are already vibe coding their next masterwork?

  I tried converting this:

  [

    {
  
      "name": "Avocado Dip",
  
      "carb": 2,
  
      "cholesterol": 5,
  
      "fiber": 0,
  
      "minerals": {
  
        "ca": 0,
  
        "fe": 0
  
      },
  
      "protein": 1,
  
      "sodium": 210,
  
      "vitamins": {
  
        "a": 0,
  
        "c": 0
  
      }
  
    }
  

  ]

  And I got:

  name,carb,cholesterol,fiber,minerals,protein,sodium,vitamins

  Avocado Dip,2,5,0,"{""ca"":0,""fe"":0}",1,210,"{""a"":0,""c"":0}"

  Which is not what I would expect.

    Sorry for the inconvenience. The problem was that my logic was working for few working types and sets of json. So, it wasn't able to recognize your need. So now I have made the logic more robust, so it can handle wide range of json types.

    Thanks for feedback. Have a Good Day!!

  { "data": { "field1": "hello", "test": [ "what", "is", "this" ] }, "something": "yay" }

  becomes

  data,something [object Object],yay

  I already knew complex types / nested objects would not work. but what makes json stronger than csv is that you can handle more complex data types and most people will use json that way too. Otherwise json would just be a less bloated xml, which is a less bloated csv. lol
