从Google电子表格单元格中解析Json

Posted 2021-04-05

在谷歌电子表格单元格中，我有这样的文字：

{"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"]};

来自Facebook API的JSON来自Supermetrics。

现在我想解析这个单元格，但这段代码不起作用： - /

我在电子表格“= parseTargeting（A1）”中使用此功能

和脚本编辑器中的这个自定义函数

 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"]+ "
";  


    }

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


    var returnString = returnVek + returnInterests;



  return returnString;

}

此函数始终返回Undefined。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"]};
"

功能 - 然后它的工作。但我需要此功能来动态地从谷歌电子表格单元格中获取价值。

我不明白： - /你能帮助解析如何从Google Spreadsheet Cell解析JSON吗？

答案

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

Sample script :

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

Note :

• 在此脚本中，它假设您的json对象位于单元格“A1”中。
• 使用此脚本时，请使用json对象将其复制并粘贴到Spreadsheet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"]+ "
";  
    }
    var returnVek = "Vek:"+minAge + " - " + maxAge+" 
";
    var returnInterests = "Zájmy:"+interests;
    Logger.log(returnInterests);
    var returnString = returnVek + returnInterests;
  } else {
    var returnString = "No data";
  }
  return returnString; // Added
}

Note :

• 对于样本表，“A4”和“A7”的值在var interestsBasics = content["flexible_spec"][0]["interests"][0]["name"];发生错误。因为价值中没有flexible_spec的财产。
