This article describes the formula syntax and usage of the MINA function in Microsoft Excel.
Description
Returns the smallest value in the list of arguments.
Syntax
MINA(value1, [value2], ...)
The MINA function syntax has the following arguments:

Value1, value2, ... Value1 is required, subsequent values are optional. 1 to 255 values for which you want to find the smallest value.
Remarks

Arguments can be the following: numbers; names, arrays, or references that contain numbers; text representations of numbers; or logical values, such as TRUE and FALSE, in a reference.

If an argument is an array or reference, only values in that array or reference are used. Empty cells and text values in the array or reference are ignored.

Arguments that contain TRUE evaluate as 1; arguments that contain text or FALSE evaluate as 0 (zero).

Arguments that are error values or text that cannot be translated into numbers cause errors.

If the arguments contain no values, MINA returns 0.

If you do not want to include logical values and text representations of numbers in a reference as part of the calculation, use the MIN function.
Example
Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
