Google Apps 脚本：仅复制和粘贴公式

Question

我只需要使用 Google Apps 脚本在电子表格中复制和粘贴公式

var range = activeSheet.getRange(targetRow-1, 1, 1, activeSheet.getLastColumn());
range.copyTo(activeSheet.getRange(targetRow, 1, 1, activeSheet.getLastColumn()), {contentsOnly:false});

这给了我完整的信息，包括公式和数据。但是，我只想复制公式（没有数据）。

CopyFormulasToRange 很遗憾不存在。

Answer 1

使用 getFormulasR1C1 和 setFormulasR1C1 复制公式并保留相对引用。例如：

  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1");

  var currentRow = sheet.getLastRow();

  var sourceRange = sheet.getRange(currentRow, 3, 1, 4);
  var sourceFormulas = sourceRange.getFormulasR1C1();

  currentRow++;

  var targetRange = sheet.getRange(currentRow, 3, 1, 4);
  targetRange.setFormulasR1C1(sourceFormulas);

以下函数将仅复制公式。它具有从哪一行和哪一列开始获取公式的用户设置。

function copyFormulas() {
  var activeSheet,numberOfSourceColumnsToGet,sourceColumnStart,sourceFormulas,sourceRange,
      sourceRowStart,targetColumn,targetRange,targetRowStart;

  //USER INPUT

  sourceRowStart = 1; //Row to start getting formulas from
  sourceColumnStart = 2; //Column to start getting formulas from
  numberOfSourceColumnsToGet = 1; //Number of columns to get formulas from

  targetRowStart = 1; //Row to start copying formulas to
  targetColumn = 3; //Column to start copying formulas to

  //END OF USER INPUT

  activeSheet = SpreadsheetApp.getActiveSheet();
  sourceRange = activeSheet.getRange(sourceRowStart, sourceColumnStart, activeSheet.getLastRow(), numberOfSourceColumnsToGet);

  sourceFormulas = sourceRange.getFormulas();//Get only formulas from the source range

  targetRange = activeSheet.getRange(targetRowStart,targetColumn,sourceFormulas.length,sourceFormulas[0].length);

  targetRange.setFormulas(sourceFormulas);//Copy the formulas to the target range
}
