Adding number to multiple cells in google sheets - without dragging corner or copying background col-CodePudding

I've tried to figure out multiple ways to do this. It seems like it should be simple enough but I haven't been able to figure out how to select multiple cells to fill them with the same number - without changing a preexisting background color that I have across some cells.

If I do the usual select the cell, drag the corner routine, I end up copying the background color in unintentional ways.

I literally just need the same number (.25) assigned to almost every cell.

CodePudding user response：

try:

=INDEX(SEQUENCE(5; 6; 1; 1)*0.25)

where 5 is row and 6 is column

CodePudding user response：

Use this formula

=ArrayFormula(IF(ISNUMBER(RANDARRAY(COUNTA(A:A),COUNTA(1:1))), 0.25, ""))

Explanation

COUNTA(A:A) is the number of columns in the range A:A.
COUNTA(1:1) is the number of rows in the range 1:1 the "header".
You can replace it with hard coded number

Example: 12 columns and 10 rows.

=ArrayFormula(IF(ISNUMBER(RANDARRAY(12,10)), 0.25, ""))
