single quote ' as the first or last character of the name
The single quote is Unicode U+0027, also known as apostrophe. Other single-quote characters, similar to apostrophe, are allowed, such as ʼ ‛ and ‚.
You can set a prefix for the names of new sheets you create. Choose and enter the prefix name in Prefix name for new worksheet.
In cell references, a sheet name must be enclosed in single quotes ' when the name contains other characters than alphanumeric or underscore. A single quote contained within a name has to be escaped by doubling it (two single quotes).
For example, you want to reference the cell A1 on a sheet named This year's sheet.
The reference must be enclosed in single quotes, and the one single quote inside the name must be doubled: 'This year''s sheet'.A1
