EXPAND function

PRO

The EXPAND function in Jspreadsheet Formulas Pro is a useful tool for managing your spreadsheet data. It allows you to take a range of cells and break them down into individual cells. This can be highly beneficial when you want to work with specific data points within a larger dataset. Essentially, it provides a simpler way to manipulate and analyze data by focusing on each cell within a selected range.

Documentation

Expands a range of cells into individual cells.

Syntax

EXPAND(array, rows, [columns], [pad_with])

Parameter	Description
`array`	The array to be expanded.
`rows`	The number of rows for the expanded array.
`[columns]`	Optional. The number of columns for the expanded array. If not specified, the array is expanded into a single column.
`[pad_with]`	Optional. A value to pad the expanded array with when the dimensions are larger than the original array. If not specified, the additional cells remain empty.

Behavior

The EXPAND function is used to expand the range of cells referenced in a formula. It is beneficial when the data range is dynamic and can change over time. Here are some of the expected behaviors:

Empty Cells: If the range defined by the EXPAND function includes empty cells, these cells are typically ignored.
Text: If the range includes cells that contain text, the function may return an error or ignore these cells, depending on the context of the formula.
Booleans: Boolean values (TRUE/FALSE) are preserved in the expanded output.
Errors: If the range includes cells that contain errors, the EXPAND function will typically propagate these errors to the resulting calculation.
Non-Contiguous Ranges: The EXPAND function may not work correctly with non-contiguous ranges.

Common Errors

Error Name	Description
#REF!	Occurs when the expanded range goes beyond the limit of the spreadsheet.
#VALUE!	Occurs when the range includes cells that contain non-numeric values in a context where only numeric values are expected.
#N/A	Occurs when the range does not exist or cannot be expanded.
#NULL!	Occurs when the range defined is non-contiguous or disjointed.

Best practices

Always ensure that the range specified in the EXPAND function does not exceed the limit of the spreadsheet to avoid the #REF! error.

Be mindful of the data type in the range. If the formula requires numeric values, ensure that the range does not include text or boolean values to avoid the #VALUE! error.

Use the EXPAND function for ranges that are likely to change over time. This will make your formulas dynamically adapt to the changing range.

Avoid using non-contiguous ranges with the EXPAND function. This can lead to unexpected results or the #NULL! error.

Usage

A few examples using the EXPAND function.

EXPAND(A1:A3, 4)
// Returns: [[A1], [A2], [A3], [#N/A]]

EXPAND(A1:B2, 3, 3)
// Expands the 2×2 array into a 3×3 array, leaving extra cells empty.

EXPAND(A1:B2, 3, 3, 0)
// Expands the 2×2 array into a 3×3 array, filling extra cells with 0.```
