+

+  - **`$`**: Displays the dollar symbol. You can replace this with another currency symbol like **€** or **£**.
+  - **`#,##0`**: Formats numbers with a thousands separator (`,`).
+  - **`.00`**: Ensures two decimal places are always displayed.
+
+### Common Custom Format Examples
+
+- **`"€"#,##0.00`**: Formats numbers as Euros with two decimal places.
+- **`0.00%`**: Formats numbers as percentages with two decimal places.
+- **`yyyy-mm-dd`**: Displays dates in the year-month-day format.
