A forward slash in a spreadsheet program
In spreadsheet programs like Microsoft Excel, a forward slash is used in formulas for a division. For example, in the following formula, cell A1 is divided by cell B1.
When not used in a formula a forward slash with only numbers is treated as a date. For example, if you entered "2/1" in a cell, Excel treats the cell as the date "1-Feb" or "2/1/2019."
Regular expression delimiter
