Convert JSON to CSV (go package and command line tool)

json2csv's Issues

Unsupported JSON structure.

I tried converting JSON('string not struct') to CSV but got an Unsupported JSON structure. error

package main

import (
	"github.com/yukithm/json2csv"
)

func main() {
	as := `[
  {
    "id": 1,
    "name": "foo",
    "favorites": {
      "fruits": "apple",
      "color": "red"
    }
  },
  {
    "id": 2,
    "name": "bar",
    "favorites": {
      "fruits": "orange"
    }
  },
  {
    "id": 3,
    "name": "baz",
    "favorites": {
      "fruits": "banana",
      "color": "yellow"
    }
  }
]`
	csv, err := json2csv.JSON2CSV(as)
	if err != nil {
		return
	}
	println(csv)
}

Not preserve keys order

It seems like the tool can't preserve JSON keys order.

cannot instal using go get

Hi,
I'm trying to install the tool using go get method, but am getting an error:

Non-ASCII

Hey, I had problems with tool converting Arabic texts from JSON to CSV.

Improved support as replacement for npm-based json2csv

I'm looking for a go-based replacement of the npm-based json2csv but there are some features missing that still require some pre-processing of data before it can be fed into this go-based implementation:

• Support arrays of objects as input, not only line-delimited JSON
• Make it possible to output all keys found in the data without having to specify each key
• Specify a quote value (see "-q") to quote fields with

There are more functionality that may be added but these are the most important ones that prevent me from switching.
It would be great to add support for them (and maybe others) so a switch of the implementations is easier to do.

Use other styles when using the library in the code

I am trying to set a different style, however, I can't seem to know how to do that. I wonder if that is just not available or if I can do that somehow

I new a newCSVWriter that uses SlashStyle style.

Thanks for the awesome tool

Seems that WriteCSV is losing some of its data

I have noticed that some conversion (can't figure it out the pattern that is causing it) lose its data when converting the content to the csv file.

Steps to reproduce:

b := &bytes.Buffer{}
wr := json2csv.NewCSVWriter(b)
responses := []map[string]interface{}{} 

//populate responses

csvContent, err := json2csv.JSON2CSV(responses) // csvContent seems to be complete!
wr.WriteCSV(csvContent) 
wr.Flush()
b.Bytes()

At this point when I print the string of the bytes, I get 2 columns missing.

Seems that the issue happens here:

Which doesn't make sense because the value is there

please release to homebrew or docker hub

I'm trying to download and run the binary file, but macOS prevents it, because cannot verify it

Could you please release the binary file to the homebrew or to the Docker Hub?
