Drive 上的 JSON 文件到 Google 表格

Question

我的Google Drive上有一些JSON文件，我需要从中提取数据到电子表格中。 我已经尝试了来自github的ImportJson函数，但那是直接从 API 获取 JSON 文件，但我无法直接从 API 访问我驱动器上的 JSON 文件。

任何人都可以帮助我如何将存储在驱动器上的 JSON 导入到 Google 表格中。

示例 JSON 随附：

数据样本看起来像这样

Answer 1

您基本上想要检索对象中的所有嵌套属性（在您使用JSON.parse()转换了 JSON 字符串之后，并将相应的键值对写入电子表格的前两行（第 1 行中的键， value in row 2). 当 value 是一个对象时， key会写入第 1 行，但第 2 行将保持空白（例如b2b ）。

在这种情况下，您可以使用递归来迭代并从对象中检索所有嵌套的属性和值。 该功能可能是这样的：

function allProps(element, array, parent = "") {
  if (typeof element === 'object' && element !== null) {
    if (parent != "") array.push([parent, ""]);
    const entries = Object.entries(element);    
    entries.forEach(entry => {
      const nextParent = Array.isArray(element) ? "" : entry[0];              
      allProps(entry[1], array, nextParent);
    });
  } else {
    array.push([parent, element]);
  }
}

这个想法是，对于每个值，它检查该值是对象还是原始数据类型。 如果是前者， allProps被递归调用，如果是后者，键值对被添加到电子表格中。

你可以这样称呼它：

function JSON_to_Spreadsheet() {
  const id = "JSON_FILE_ID"; // Change to your FILE_ID
  const json = DriveApp.getFileById(id).getBlob().getDataAsString(); // Get JSON text from Drive file
  const obj = JSON.parse(json); // JSON text to JS object 
  let array = []; // 2D array where the output will be stored
  allProps(obj, array, parent = ""); // Call function recursively
  array = array[0].map((_, colIndex) => array.map(row => row[colIndex])); // Transpose 2D array
  const sheet = SpreadsheetApp.getActive().getActiveSheet(); // Retrieve active sheet. Change if you want to access another sheet or another spreadsheet
  sheet.getRange(1,1,array.length, array[0].length).setValues(array); // Write 2D array to your sheet.
}

输出如下所示：

编辑：

如果您希望每个ctin标题（除了第一个，在 D 列中）占据一个新行，您可以在检索 2D 数组后执行以下操作：

• 从array[0]中检索包含所有索引的array[0] ，其中标头为ctin （不包括第一个）。
• 使用这些索引，将每个ctin段添加到主数组中。
• 考虑到不同的行具有不同的长度，将数组写入工作表。 如果您想使用单个setValues （出于效率目的，建议这样做），您首先必须找到内部数组元素的最大长度，并使所有内部数组都具有此长度。

函数JSON_to_Spreadsheet可能是这样的：

function JSON_to_Spreadsheet() {
  const id = "JSON_FILE_ID"; // Change to your FILE_ID
  const json = DriveApp.getFileById(id).getBlob().getDataAsString(); // Get JSON text from Drive file
  const obj = JSON.parse(json); // JSON text to JS object 
  let array = []; // 2D array where the output will be stored
  allProps(obj, array, parent = ""); // Call function recursively
  array = array[0].map((_, colIndex) => array.map(row => row[colIndex])); // Transpose 2D array
  const ctinFirstIndex = 3; // Column D (first ctin)
  const ctinIndexes = array[0].reduce((acc, current, i) => {
    if (current === "ctin" && i !== ctinFirstIndex) {
      acc.push(i);
    } 
    return acc;
  }, []); // Find indexes for all ctin headers
  for (let i = 0; i < ctinIndexes.length; i++) {
    [0,1].forEach(rowIndex => {
      const sliced = array[rowIndex].slice(ctinIndexes[i], ctinIndexes[i + 1]); // Extract ctin segment
      sliced.unshift("","",""); // Columns A to C should be empty
      array.push(sliced); // Add each ctin segment to the 2D array
    });    
  }
  [0,1].forEach(rowIndex => array[rowIndex].splice(ctinIndexes[0])); // Remove other ctin data from first two rows
  const sheet = SpreadsheetApp.getActive().getSheetByName("Copy of Data");
  for (let i = 0; i < array.length; i = i + 2) {
    sheet.getRange(sheet.getLastRow() + 1, 1, 2, array[i].length).setValues(array.slice(i, i + 2));
  } // Write array to sheet. Rows have different dimensions, so cannot be written all at once
}

在这种情况下，输出是：

这应该适用于特定的 json 文件。 由于在驱动器中打开 JSON 文件获取文件 ID 有点困难，因此您可以使用第一个函数来获取 ID。

编辑：

当您运行第一个函数时，您可以在日志 -> 查看 -> 日志中查找 jsonfile ID。 然后在 // Change file id 下的第二个函数中插入这个 ID

//With this function you can get the ID of you json file. After running see the view -> Logs for the info.
function getDriveFileID() {

  //Change id of the drive folder found in the url
  const folderID = "1UN3xxxpE8mXjHHJJF";
  const driveFolder = DriveApp.getFolderById(folderID);
  const driveFiles = driveFolder.getFiles();

  while(driveFiles.hasNext()){
    let file = driveFiles.next();
    console.log(file.getName()," = ",file.getId());
  };
}

function JSON_from_DRIVE() {
  const ss = SpreadsheetApp.getActiveSpreadsheet();
  //change output sheetname
  const sheet = ss.getSheetByName("Data");
  //Change file id
  const file = DriveApp.getFileById("1IPyU2nxxxxx_lr0F").getBlob().getDataAsString();
  const dataAll = JSON.parse(file);
  const dataRows = dataAll['b2b'];
  
  const rowHeaders = Object.keys(dataRows[0]);
  const rows = [rowHeaders];
  for (var i = 0; i < dataRows.length; i++) {
    var rowData = [];
    for (var j = 0; j < rowHeaders.length; j++) {
      rowData.push(dataRows[i][rowHeaders[j]]); 
    }
    rows.push(rowData);
  }

  sheet.getRange(1,1,rows.length,rows[0].length).setValues(rows); 

}
