One of the common things when working with Google Sheets is to name or rename your Sheets. Google has made it so easy that you can directly change or edit the names.
1. Name a New Sheet
Step 1: Login your Google Sheet (please refer to How to Create a Google Sheet), and create a new Google Sheet by clicking "Start a new spreadsheet";
Step 2: When you first create a new Sheet, Google Sheets will automatically name it as "Untitled Spreadsheet". Click "Untitled Spreadsheet" on the left-top corner, and write the correct names in the box.
Step 3: Google Sheets will automatically save your changes (e.g., "Excel").
2. Name a Sheet
If you have the Sheet already open, you can follow the exact step 1 to step 3 as above.
Alternatively, you can change the Sheets names before you open them with the steps below:
Step 1: Click the "Edit" button right after the "Sheet" name before you open it.
Step 2: Click "Rename" from the drop-down list;
Step 3: Type the proper name in the rename box and click "OK".
