You can easily convert the first letter of each word to uppercase by following these steps:

• Open your file in Text Editor.
• Press "CTRL + H" to open the "Find and Replace" window.
• In the "Find" textbox, type ^(.)
• In the "Replace with" textbox, type \u\1
• Check the "Regular expression" box
• Click on the "Replace All" button

All lowercase first letters will be converted to uppercase.
