SHEETS function

PRO

The SHEETS function in Jspreadsheet Formulas Pro is a simple tool that tells you how many sheets are in a specific reference. This could be particularly useful if you're working with a large workbook and want a quick way to count all the sheets. You simply input the reference you're interested in and it will return the total number of sheets included. It's a handy way to keep track of your data organization in Jspreadsheet.

Documentation

Returns the number of sheets in a reference.

Syntax

SHEETS([reference])

Parameter	Description
`reference`	Optional. A reference to a cell or range of cells in the same workbook. If omitted, returns the number of sheets in the entire workbook.

Behavior

The SHEETS function in returns the number of sheets in a reference. The behavior of the SHEETS function is as follows:

The SHEETS function counts all the sheets in the workbook if no argument is provided.
If a reference is provided, the SHEETS function will count all the sheets in the workbook which the reference spans.
Empty cells, text, booleans, and errors are irrelevant to the SHEETS function as it only counts the number of sheets.
The SHEETS function doesn't evaluate the contents of the sheets; it just counts the number of sheets.

Common Errors

Error	Description
#REF!	This error occurs if the provided reference is invalid.
#N/A	This error occurs if the reference does not exist.
#VALUE!	This error occurs if the supplied argument is a non-numeric value.

Best practices

Always ensure that the references provided to the SHEETS function are valid to avoid errors.

Use the SHEETS function without any arguments to get the total number of sheets in a workbook.

Be cautious of the workbook structure when using the SHEETS function as adding or removing sheets will affect the output of the function.

Use the SHEETS function in combination with other functions like INDEX and MATCH to navigate large workbooks more effectively.

Usage

A few examples using the SHEETS function.

SHEETS() returns the total number of sheets in the workbook  
SHEETS(Annual!A1:C10) returns the number of sheets that contain data referenced in Annual!A1:C10  
SHEETS(Sheet3!D4:E8) returns 1 if Sheet3 is the only sheet containing data referenced in the specified range
