forEach 数组出现错误类型错误：无法读取未定义的属性“forEach”

Question

im trying to clean some sheets, individually i make it work uncommenting and changing sheet name

function doClean(sheet) 
{
// var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Resultado");

var LR = sheet.getLastRow();
var LC = sheet.getLastColumn();

sheet.getRange(1,1,LR,LC).getDisplayValues()
sheet.createTextFinder("-").matchEntireCell(true).replaceAllWith("");
sheet.createTextFinder("0").matchEntireCell(true).replaceAllWith("");
sheet.createTextFinder("0,00").matchEntireCell(true).replaceAllWith("");
sheet.createTextFinder("0,0000").matchEntireCell(true).replaceAllWith("");
};

but when when i try to group in array and execute with foreach

function doCleanSheets() {
 var sheet = ["BLC", "Balanço", "DRE", "Resultado", "FLC", "Fluxo", "DVA", "Valor"];
 SpreadsheetApp.getActive().sheet.forEach(doClean);
};

im getting error

TypeError: Cannot read property 'forEach' of undefined doCleanSheets @ - 10x_to_11x.gs:87

line 87 is SpreadsheetApp.getActive().sheet.forEach(doClean);

searched for error, but results were way more complex than my case, and i couldnt apply

Answer 1

When I saw your script, unfortunately, SpreadsheetApp.getActive() has no property of sheet . By this, such error occurs. When you want to use the sheet names of sheet in the forEach, how about the following modification?

Modified script:

Please modify doCleanSheets as follows.

function doCleanSheets() {
  var sheet = ["BLC", "Balanço", "DRE", "Resultado", "FLC", "Fluxo", "DVA", "Valor"];
  var sheets = SpreadsheetApp.getActive().getSheets().filter(s => sheet.includes(s.getSheetName()));
  sheets.forEach(doClean);
}

References:

• getActive()
• getSheets()

Answer 2

Try it this way:

function doClean(sheet) {
  var LR = sheet.getLastRow();
  var LC = sheet.getLastColumn();
  sheet.getRange(1, 1, LR, LC).getDisplayValues()
  sheet.createTextFinder("-").matchEntireCell(true).replaceAllWith("");
  sheet.createTextFinder("0").matchEntireCell(true).replaceAllWith("");
  sheet.createTextFinder("0,00").matchEntireCell(true).replaceAllWith("");
  sheet.createTextFinder("0,0000").matchEntireCell(true).replaceAllWith("");
};
function doCleanSheets() {
 var sheet = ["BLC", "Balanço", "DRE", "Resultado", "FLC", "Fluxo", "DVA", "Valor"];
 sheet.forEach(sh => doClean(SpreadsheetApp.getActive().geSheetByName(sh)));
};
