MINIFS function
Returns the minimum of the values of cells in a range that meets multiple criteria in multiple ranges.
This function is available since LibreOffice 5.2.
MINIFS(Func_Range; Range1; Criterion1[; Range2; Criterion2][; … ; [Range127; Criterion127]])
Func_Range – required argument. A range of cells, a name of a named range or a label of a column or a row containing values for calculating the minimum.
Range1 – required argument. It is a range of cells, a name of a named range, or a label of a column or a row, to which the corresponding criterion is to be applied.
Criterion1 – required argument. A string expression representing a logical condition or a cell reference to such string expression. The expression can contain text, numbers, regular expressions or wildcards (if enabled in calculation options).
Range2 – Optional. Range2 and all the following mean the same as Range1.
Criterion2 – Optional. Criterion2 and all the following mean the same as Criterion1.
The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every character with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in .
When using functions where one or more arguments are search criteria strings that represents a regular expression, the first attempt is to convert the string criteria to numbers. For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match. However, when switching to a locale where the decimal separator is not the dot makes the regular expression conversion work. To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as ".[0]" or ".\0" or "(?i).0".
Func_Range and Range1, Range2... must have the same size, otherwise the function returns err:502  Invalid argument.
The logical relation between criteria can be defined as logical AND (conjunction). In other words, if and only if all given criteria are met, a value from the corresponding cell of the given Func_Range is taken into calculation.
The function can have up to 255 arguments, meaning that you can specify 127 criteria ranges and criteria for them.
If a cell contains TRUE, it is treated as 1, if a cell contains FALSE – as 0 (zero).
This function is part of the Open Document Format for Office Applications (OpenDocument) standard Version 1.2. (ISO/IEC 26300:22015)

In all examples below, ranges for calculation contain the row #6, which is ignored because it contains text.
Simple usage
=MINIFS(B2:B6;B2:B6;"<35")
Calculates the minimum of values of the range B2:B6 that are lower than or equal to 20. Returns 17.
=MINIFS(C2:C6;B2:B6;">=20";C2:C6;">90")
Calculates the minimum of values of the range C2:C6 that are lower than 90 and correspond to cells of the B2:B6 range with values greater than or equal to 20. Returns 190.
Using regular expressions and nested functions
=MINIFS(C2:C6;B2:B6;">"&MIN(B2:B6);B2:B6;"<"&MAX(B2:B6))
Calculates the minimum of values of the range C2:C6 that correspond to all values of the range B2:B6 except its minimum and minimum. Returns 65.
=MINIFS(C2:C6;A2:A6;".*book";B2:B6;"<="&MAX(B2:B6))
Calculates the minimum of values of the range C2:C6 that correspond to all cells of the A2:A6 range starting with "pen" and to all cells of the B2:B6 range except its minimum. Returns 180.
Reference to a cell as a criterion
If you need to change a criterion easily, you may want to specify it in a separate cell and use a reference to this cell in the condition of the MINIFS function. For example, the above function can be rewritten as follows:
=MINIFS(C2:C6;A2:A6;".*"&E2;B2:B6;"<"&MAX(B2:B6))
If E2 = "book", the function returns 180, because the reference to the cell is substituted with its content.
