javascript - 从 Google 电子表格单元格中解析 Json

Question

在谷歌电子表格单元格中，我有这个文本:
{"age_max":65,"age_min":18,"flexible_spec":[{"interests":[{"id":"6002867432822","name":"Beauty"},{"id":"6002991733794","name":"Beauty & Care"},{"id":"6003177110133","name":"Natural Beauty"},{"id":"6003211042524","name":"Health and Beauty Care"},{"id":"6003393295343","name":"Health And Beauty"},{"id":"6003460329503","name":"Beautiful Skin"},{"id":"6004111438209","name":"Facial care"}]}],"genders":[2],"geo_locations":{"countries":["SK"],"location_types":["home","recent"]},"locales":[2,33],"targeting_optimization":"none","publisher_platforms":["facebook"],"facebook_positions":["feed","right_hand_column","instant_article"],"device_platforms":["mobile","desktop"]};
它来自 Facebook API 的 JSON 来自 Supermetrics。

现在我想解析这个单元格，但是这段代码不起作用:-/

我在电子表格“=parseTargeting(A1)”中使用这个函数

以及脚本编辑器中的这个自定义功能。

 function parseTargeting(jsonData) {




    var flexible_spec = jsonData["flexible_spec"];
    var maxAge = jsonData["age_max"];
    var minAge = jsonData["age_min"];

    var interestsBasics = jsonData["flexible_spec"][0]["interests"][0]["name"];


    var interestsBasicsCelkem = jsonData["flexible_spec"][0]["interests"].length-1;
    var interests = "";
    var output = [];

    for(var i = 0; i<=interestsBasicsCelkem; i++){

      interests += jsonData["flexible_spec"][0]["interests"][i]["name"]+ "\n";  


    }

    var returnVek = "Vek:"+minAge + " - " + maxAge+" \n";
    var returnInterests = "Zájmy:"+interests;


    var returnString = returnVek + returnInterests;



  return returnString;

}

此函数始终返回未定义。如果我添加此代码

" var jsonData = {"age_max":65,"age_min":18,"flexible_spec":[{"interests":[{"id":"6002867432822","name":"Beauty"},{"id":"6002991733794","name":"Beauty & Care"},{"id":"6003177110133","name":"Natural Beauty"},{"id":"6003211042524","name":"Health and Beauty Care"},{"id":"6003393295343","name":"Health And Beauty"},{"id":"6003460329503","name":"Beautiful Skin"},{"id":"6004111438209","name":"Facial care"}]}],"genders":[2],"geo_locations":{"countries":["SK"],"location_types":["home","recent"]},"locales":[2,33],"targeting_optimization":"none","publisher_platforms":["facebook"],"facebook_positions":["feed","right_hand_column","instant_article"],"device_platforms":["mobile","desktop"]};
"

发挥作用 - 然后是它的工作。但我需要这个函数来动态地从谷歌电子表格单元格中获取值(value)。

我不明白:-/你能帮助如何从谷歌电子表格单元中解析 JSON 吗？

Answer 1

这个示例脚本怎么样？对于您的 json 对象，有 ;在对象的末尾。这样，它就无法解析。所以;被删除并解析它。

示例脚本:

function myFunction() {
  var ss = SpreadsheetApp.getActiveSheet();
  var obj = JSON.parse(ss.getRange("A1").getValue().replace(";", ""));
  var res = parseTargeting(obj);
  Logger.log(res)
}

笔记 :

在此脚本中，它假设您的 json 对象位于单元格“A1”中。

当您使用此脚本时，请将其复制并粘贴到带有 json 对象的电子表格上的脚本编辑器中。

如果我误解了你的问题，请告诉我。我想修改它。

编辑 :

function parseTargeting(range) {
  var content = JSON.parse(range.replace(";", "")); // Modified
  if( range != "undefined" ){
    var flexible_spec = content["flexible_spec"];
    var maxAge = content["age_max"];
    var minAge = content["age_min"];
    var interestsBasics = content["flexible_spec"][0]["interests"][0]["name"];
    Logger.log(interestsBasics);
    var interestsBasicsCelkem = content["flexible_spec"][0]["interests"].length-1;
    var interests = "";
    var output = [];
    for(var i = 0; i<=interestsBasicsCelkem; i++){
      interests += content["flexible_spec"][0]["interests"][i]["name"]+ "\n";  
    }
    var returnVek = "Vek:"+minAge + " - " + maxAge+" \n";
    var returnInterests = "Zájmy:"+interests;
    Logger.log(returnInterests);
    var returnString = returnVek + returnInterests;
  } else {
    var returnString = "No data";
  }
  return returnString; // Added
}

笔记 :

对于您的 sample 表，“A4”和“A7”的值在 var interestsBasics = content["flexible_spec"][0]["interests"][0]["name"]; 处出现错误。 .因为没有 flexible_spec 的属性在值(value)。
