使用 indexOf 在谷歌表中自定义 function

Question

I've got a list of emails that I need to clean and identify which of these emails are company emails (ie info@, hello@, etc)

I've had an idea to add rows in one google sheet, then check this against another google sheet with a column of company alias'. This will then return True of False in the column Company Alias? in the Input sheet.

Here is my Google sheet example.

I think it needs to iterate through the values of the second sheet and compare for email 1 field in the first sheet to see if it contains that value. I have made an apps script below:

function CHECKALIAS(x) {

var app = SpreadsheetApp;  
var aliasSheet = app.getActive().getSheetByName('Company_Alias').getRange(2, 1, 45, 1);  
var aliasRange = aliasSheet.getValues();
var str = x;

if(str.indexOf(aliasRange) !== -1){
  return false;
  } else {
  return true;
  }  

}

I get the below error:

TypeError: Cannot read property 'indexOf' of undefined (line 13, file "Code")

Answer 1

Are you running the function without passing it a value? It's giving you the error because str has no value.

Anyway, there's no need for a custom function here. This will return true if there's a match with one of the aliases.

=REGEXMATCH(A1, JOIN("|",FILTER(Company_Alias!A2:A, NOT(ISBLANK(Company_Alias!A2:A)))))

Answer 2

str is a string and aliasRange is an array. Instead of searching for the array in the string, you should search for the string in the array.

Another problem is that .getValues() returns an array of arrays:

[["info @"], ["support @"], ["sales @"], ...]. 

To transform it into a 1D array, use the flat() function:

function CHECKALIAS(x) {
  let app = SpreadsheetApp;
  let aliasSheet = app.getActive().getSheetByName('Company_Alias').getRange(2, 1, 45, 1);
  let aliasRange = aliasSheet.getValues().flat(); // Transforms 2D array in 1D

  let userDomain = x.split('@'); // split "admin@somedomain.com"  into  [ "admin", "somedomain.com" ]
  let usr = userDomain[0] + '@'; // "admin@

  return aliasRange.indexOf(usr) !== -1; // Is usr in aliasRange?
}
