谷歌应用脚​​本：解析 JSON 并将它们写入谷歌电子表格

Question

我已经设法使用 Google Apps 脚本下载了一个 JSON 文件。很快，我发现我的 JSON 比 Internet 上的示例（包括这里）要复杂一些。

var json = {"block1":[{"TRD_DD":"2021/12/22","MKTCAP":"2,208,300,470,743,887","FORN_HD_MKTCAP":"740,740,079,190,175","MKTCAP_RTO":"33.54","LIST_SHRS":"61,701,475,584","FORN_HD_SHRS":"11,191,374,601","LIST_SHRS_RTO":"18.14"},{"TRD_DD":"2021/12/21","MKTCAP":"2,200,896,109,564,335","FORN_HD_MKTCAP":"736,382,905,931,787","MKTCAP_RTO":"33.46","LIST_SHRS":"61,701,475,584","FORN_HD_SHRS":"11,198,948,564","LIST_SHRS_RTO":"18.15"},{"TRD_DD":"2021/12/20","MKTCAP":"2,191,456,183,748,063","FORN_HD_MKTCAP":"731,379,899,525,089","MKTCAP_RTO":"33.37","LIST_SHRS":"61,698,916,232","FORN_HD_SHRS":"11,215,916,966","LIST_SHRS_RTO":"18.18"}],"CURRENT_DATETIME":"2021.12.22 PM 04:24:06"}

“Block1”中有更多数组，但我缩短了长度。请考虑多行（我认为大约 500 行）

我想给出不同的列名，例如“AAA”、“BBB”、“CCC”、“DDD”、“EEE”、“FFF”、“GGG”，而不是“TRD_DD”、“MKTCAP”、 “FORN_HD_MKTCAP”、“MKTCAP_RTO”、“LIST_SHRS”、“FORN_HD_SHRS”、“LIST_SHRS_RTO”。 每行都应该插入同名的每个值（抱歉，StackOverflow 不允许我插入图片。这很难解释）。

如果可能的话，我想将所有数字更改为数字而不是字符串。

我是处理javascript的初学者，所以非常难！！！ 有没有人可以帮助我？如果有的话，将不胜感激。

  var json = UrlFetchApp.fetch(url, options);
  

// Object for converting the keys.

  json.block1 = json.block1.map(o => Object.fromEntries(Object.entries(o).map(([k, v]) => [obj[k], v.includes(",") ? v.split(",").map(e => Number(e)) : v])));

  console.log(json)

// Put the values to Spreadsheet.
  var header = ["AAA", "BBB", "CCC", "DDD", "EEE", "FFF", "GGG"];
  var values = json.block1.flatMap(o => {

    var max = Math.max(...temp.map(r => Array.isArray(r) ? r.length : 1));
    temp = temp.map(r => {

        return r.length == max ? r : [...r, ...Array(max - r.length).fill("")];
      }
      return [r, ...Array(max - 1).fill("")]; // or return Array(max).fill(r);
    })
    return temp[0].map((_, c) => temp.map(r => r[c]));
  });
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("sheet126"); // Please set the sheet name.
  sheet.getRange(sheet.getLastRow() + 1, 1, values.length, values[0].length).setValues(values);

现在它说

TypeError: Cannot read property 'map' of undefined
foreign_daily   @ Foreign_daily.gs:42

再次感谢，田池！

我相信你的目标如下。

• 您想将密钥从 "TRD_DD", "MKTCAP", "FORN_HD_MKTCAP", "MKTCAP_RTO", "LIST_SHRS", "FORN_HD_SHRS", "LIST_SHRS_RTO" 更改为 "AAA", "BBB", "CCC", "DDD", "EEE", "FFF", "GGG"。
• 您希望将"2,208,300,470,743,887" 等值转换为[2,208,300,470,743,887] 等数字。
• 您希望使用 Google Apps 脚本实现此目的。

在这种情况下，下面的示例脚本怎么样？

示例脚本：

// This is from your question.
var json = {"block1":[{"TRD_DD":"2021/12/22","MKTCAP":"2,208,300,470,743,887","FORN_HD_MKTCAP":"740,740,079,190,175","MKTCAP_RTO":"33.54","LIST_SHRS":"61,701,475,584","FORN_HD_SHRS":"11,191,374,601","LIST_SHRS_RTO":"18.14"},{"TRD_DD":"2021/12/21","MKTCAP":"2,200,896,109,564,335","FORN_HD_MKTCAP":"736,382,905,931,787","MKTCAP_RTO":"33.46","LIST_SHRS":"61,701,475,584","FORN_HD_SHRS":"11,198,948,564","LIST_SHRS_RTO":"18.15"},{"TRD_DD":"2021/12/20","MKTCAP":"2,191,456,183,748,063","FORN_HD_MKTCAP":"731,379,899,525,089","MKTCAP_RTO":"33.37","LIST_SHRS":"61,698,916,232","FORN_HD_SHRS":"11,215,916,966","LIST_SHRS_RTO":"18.18"}],"CURRENT_DATETIME":"2021.12.22 PM 04:24:06"};

// Object for converting the keys.
var obj = {"TRD_DD": "AAA", "MKTCAP": "BBB", "FORN_HD_MKTCAP": "CCC", "MKTCAP_RTO": "DDD", "LIST_SHRS": "EEE", "FORN_HD_SHRS": "FFF", "LIST_SHRS_RTO": "GGG"};

// Converting keys.
json.block1 = json.block1.map(o => Object.fromEntries(Object.entries(o).map(([k, v]) => [obj[k], v.includes(",") ? v.split(",").map(e => Number(e)) : v])));

console.log(json)

参考：

• map()

关于你评论中的Another goal I'd like to achieve is to upload it into a google sheet.，下面的示例脚本怎么样？

示例脚本：

// This is from your question.
var json = {"block1":[{"TRD_DD":"2021/12/22","MKTCAP":"2,208,300,470,743,887","FORN_HD_MKTCAP":"740,740,079,190,175","MKTCAP_RTO":"33.54","LIST_SHRS":"61,701,475,584","FORN_HD_SHRS":"11,191,374,601","LIST_SHRS_RTO":"18.14"},{"TRD_DD":"2021/12/21","MKTCAP":"2,200,896,109,564,335","FORN_HD_MKTCAP":"736,382,905,931,787","MKTCAP_RTO":"33.46","LIST_SHRS":"61,701,475,584","FORN_HD_SHRS":"11,198,948,564","LIST_SHRS_RTO":"18.15"},{"TRD_DD":"2021/12/20","MKTCAP":"2,191,456,183,748,063","FORN_HD_MKTCAP":"731,379,899,525,089","MKTCAP_RTO":"33.37","LIST_SHRS":"61,698,916,232","FORN_HD_SHRS":"11,215,916,966","LIST_SHRS_RTO":"18.18"}],"CURRENT_DATETIME":"2021.12.22 PM 04:24:06"};

// Object for converting the keys.
var obj = {"TRD_DD": "AAA", "MKTCAP": "BBB", "FORN_HD_MKTCAP": "CCC", "MKTCAP_RTO": "DDD", "LIST_SHRS": "EEE", "FORN_HD_SHRS": "FFF", "LIST_SHRS_RTO": "GGG"};

// Converting keys.
json.block1 = json.block1.map(o => Object.fromEntries(Object.entries(o).map(([k, v]) => [obj[k], v.includes(",") ? v.split(",").map(e => Number(e)) : v])));

console.log(json)

// Put the values to Spreadsheet.
var header = ["AAA", "BBB", "CCC", "DDD", "EEE", "FFF", "GGG"];
var values = json.block1.flatMap(o => {
  var temp = header.map(h => o[h]);
  var max = Math.max(...temp.map(r => Array.isArray(r) ? r.length : 1));
  temp = temp.map(r => {
    if (Array.isArray(r)) {
      return r.length == max ? r : [...r, ...Array(max - r.length).fill("")];
    }
    return [r, ...Array(max - 1).fill("")]; // or return Array(max).fill(r);
  })
  return temp[0].map((_, c) => temp.map(r => r[c]));
});
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1"); // Please set the sheet name.
sheet.getRange(sheet.getLastRow() + 1, 1, values.length, values[0].length).setValues(values);

• 在上述脚本中，如果您只想为一个值嵌入相同的值，请将return [r, ...Array(max - 1).fill("")]; 替换为return Array(max).fill(r);。

新增2：

根据您的以下回复，

然而，有一点是，转换为数字并不是我想要的。逗号“，”不分隔不同的数字，而只是货币计数的分隔符，例如 100 万美元（1,000,000 美元）。我想要“1,000,000”到“1000000”，而不是 1 和 000 和 000。

下面的示例脚本怎么样？

示例脚本：

// Object for converting the keys.
var obj = {"TRD_DD": "AAA", "MKTCAP": "BBB", "FORN_HD_MKTCAP": "CCC", "MKTCAP_RTO": "DDD", "LIST_SHRS": "EEE", "FORN_HD_SHRS": "FFF", "LIST_SHRS_RTO": "GGG"};

json.block1 = json.block1.map(o => Object.fromEntries(Object.entries(o).map(([k, v]) => [obj[k], v.includes(",") ? v.replace(/,/g, "") : v])));
// or json.block1 = json.block1.map(o => Object.fromEntries(Object.entries(o).map(([k, v]) => [obj[k], v.includes(",") ? Number(v.replace(/,/g, "")) : v])));

var header = ["AAA", "BBB", "CCC", "DDD", "EEE", "FFF", "GGG"];
var values = json.block1.map(o => header.map(h => o[h]));
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1"); // Please set the sheet name.
sheet.getRange(sheet.getLastRow() + 1, 1, values.length, values[0].length).setValues(values);
