sheetsbetween

Sheetsbetween is a term used in discussions of spreadsheet automation to describe the operation of identifying the subset of sheets that lie between two specified sheets in a workbook. It is not a universally standardized function, but it may refer to either a function that returns the names of intervening sheets or a value representing their count.

In practice, sheetsbetween can take two endpoint sheet references and determine which sheets appear in the sequence between them, inclusive or exclusive depending on the design. For example, with sheets named Sheet1, Sheet2, Sheet3, and Sheet4, asking for the sheets between Sheet2 and Sheet4 would yield Sheet3 as the intervening sheet, and a count of 1 if the endpoints are excluded.

Implementation approaches vary by platform. In VBA for Excel, one can locate the indices of the two sheets in the workbook.Sheets collection, compute the range between these indices, and return either the list of sheet names or the number of sheets in that range. In Python with libraries such as openpyxl, the workbook’s worksheet list provides an ordered sequence from which the intervening slice can be derived. Similar logic applies to other spreadsheet APIs, including Google Sheets API, where sheet order information is used to determine the interval.

Edge cases include when the sheets are the same, when the first occurs after the second, or when a specified sheet name does not exist. Proper error handling and clear definitions of inclusive versus exclusive behavior are important for predictable results.
