How to remove duplicate names and mails in numbers

To remove duplicate names and emails in Numbers, you can follow these steps:

Method 1: Using the "Remove Duplicates" feature

Select the entire table by pressing Cmd + A (or Ctrl + A on a PC).
Go to the "Data" menu and select "Remove Duplicates".
In the "Remove Duplicates" dialog box, select the columns that contain the names and emails you want to remove duplicates from (e.g., "Name" and "Email").
Click "Remove Duplicates" to remove any duplicate rows.

Method 2: Using a formula

Select the entire table by pressing Cmd + A (or Ctrl + A on a PC).
Insert a new column to the right of the table by going to the "Insert" menu and selecting "Column".
In the new column, enter the following formula: =IF(COUNTIF(A:A, A2)>1, "", A2)
- Replace A:A with the range of cells that contains the names and emails.
- Replace A2 with the cell reference of the first cell in the column.
Copy the formula down to the rest of the cells in the new column.
Select the entire table by pressing Cmd + A (or Ctrl + A on a PC).
Go to the "Data" menu and select "Remove Duplicates".
In the "Remove Duplicates" dialog box, select the new column that contains the formula.
Click "Remove Duplicates" to remove any duplicate rows.

Method 3: Using a script

Select the entire table by pressing Cmd + A (or Ctrl + A on a PC).
Go to the "Tools" menu and select "Script Editor".

In the script editor, enter the following code:

function removeDuplicates() {
var table = SpreadsheetApp.getActiveSheet().getRange("A1:B10"); // adjust the range to match your table
var data = table.getValues();
var uniqueData = [];
for (var i = 0; i < data.length; i++) {
 var row = data[i];
 var exists = false;
 for (var j = 0; j < uniqueData.length; j++) {
   if (row[0] === uniqueData[j][0] && row[1] === uniqueData[j][1]) {
     exists = true;
     break;
   }
 }
 if (!exists) {
   uniqueData.push(row);
 }
}
table.clearContent();
table.setValues(uniqueData);
}

Save the script by clicking "File" > "Save" (or press Cmd + S on a Mac).
Go back to your Numbers document and select the entire table by pressing Cmd + A (or Ctrl + A on a PC).
Go to the "Tools" menu and select "Run Script".
Select the script you just created and click "Run" to remove the duplicates.

Note: The above methods assume that the names and emails are in separate columns. If they are in the same column, you may need to modify the formulas or script accordingly.
