How to make changes small to caps in mail id

You want to know how to make small changes to a mail ID, specifically converting some characters to uppercase. Here are a few ways to do it:

Method 1: Using the UPPER() function in Google Sheets or Microsoft Excel

1. Open your spreadsheet or document.
2. Enter the mail ID in a cell.
3. Use the UPPER() function to convert specific characters to uppercase. For example, if you want to convert the first letter of the mail ID to uppercase, use the formula: =UPPER(LEFT(A1,1))&MID(A1,2)
   • A1 is the cell containing the mail ID.
   • LEFT(A1,1) extracts the first character of the mail ID.
   • UPPER() converts the first character to uppercase.
   • MID(A1,2) extracts the rest of the mail ID (starting from the second character).
   • The & symbol concatenates the two parts.
4. Copy the formula to the rest of the cells in the column.

Method 2: Using regular expressions in Google Sheets or Microsoft Excel

1. Open your spreadsheet or document.
2. Enter the mail ID in a cell.
3. Use the REGEXREPLACE() function to convert specific characters to uppercase. For example, if you want to convert the first letter of the mail ID to uppercase, use the formula: =REGEXREPLACE(A1,"^([a-z])","U$1")
   • A1 is the cell containing the mail ID.
   • ^([a-z]) matches the first lowercase letter (any lowercase letter at the beginning of the string).
   • U$1 replaces the matched letter with its uppercase equivalent.
4. Copy the formula to the rest of the cells in the column.

Method 3: Using a text editor or online tool

1. Open a text editor like Notepad, TextEdit, or Sublime Text.
2. Copy the mail ID into the editor.
3. Use the "Find and Replace" feature to convert specific characters to uppercase. For example, if you want to convert the first letter of the mail ID to uppercase, use the following steps:
   • Find: ^. (matches any character at the beginning of the string)
   • Replace: \U& (converts the matched character to uppercase)
4. Copy the modified mail ID.

Remember to test the modified mail ID to ensure it's valid and functional.
