## Cell Name Requirements

When naming a cell, the cell name:

- Cannot start with a number.
- Can only contain the following characters: A-Z, a-z, 0-9 and the underscore "_" character. You cannot use spaces or non-English language characters.
- Can contain a minimum of 1 character and a maximum of 127 characters.
- Cannot be cell locations or have the form of cell locations (such as B2 or B22222).
- Must be unique. There cannot be a duplicate Cell Name within the same sheet, regardless of case.
  For instance, you cannot have one Cell Name as "test" and the other as "Test". In this case, a suffix is added to the latter Cell Name, such as "Test_1".

Note: Two or more names cannot reference the same cell in a given sheet.
