Chord data for jazz standards

I recently started playing jazz on bass guitar. So naturally, I also recently started writing software for facilitating jazz practice.

As a basis for a number of my projects, I needed access to chord data from a corpus of jazz standards. The best source I found was the database of user-submitted scores for the IReal mobile app: https://www.irealpro.com/main-playlists

I've been converting these to an easy-to parse json format. The current database of songs can be found here:

Here is an example score:   

  

  {
  "Title": "Alone Together",
  "Composer": "Schwartz Arthur",
  "Key": "D-",
  "Rhythm": "Medium Swing",
  "Sections": [
    {
      "Label": "A",
      "MainSegment": {
        "Chords": "Dm6|Em7b5,A7b9|Dm6|Em7b5,A7b9|Dm6|Am7b5,D7b9|Gm7|Gm7|Bm7,E7|Gm7,C7|Fmaj7|Em7b5,A7b9"
      },
      "Endings": [
        {
          "Chords": "Dmaj7|D(Em7b5),(A7b9)"
        },
        {
          "Chords": "Dmaj7|Dmaj7"
        }
      ]
    },
    {
      "Label": "B",
      "MainSegment": {
        "Chords": "Am7b5|D7b9|Gm6|Gm6|Gm7b5|C7b9|Fmaj7|Em7b5,A7b9"
      },
      "Endings": []
    },
    {
      "Label": "A",
      "MainSegment": {
        "Chords": "Dm6|Em7b5,A7b9|Dm6|Em7b5,A7b9|Dm6,Bm7b5|Bb7,A7b9|Dm6|Em7b5,A7b9"
      },
      "Endings": []
    }
  ]
}
