获取列中的最后一个非空单元格

Question

I have a script that is adding or substracting a value (picked up in M2 cell) in each cell of a selected range (I mean a range that I can select with the mouse):

 function moreLess() { var ss = SpreadsheetApp.getActive(); var sel = ss.getSelection().getActiveRangeList().getRanges(); for (var i=0; i<sel.length; i++) { var range = sel[i]; var values = range.getValues(); var number = SpreadsheetApp.getActive().getSheetByName("sommaire_redac").getRange('M2').getValue(); for (var j=0; j<values.length; j++) { for (var k=0; k<values[0].length; k++) { values[j][k] += number; } } range.setValues(values); } }

This works. But instead of selecting all the cells in which I want add or substract a value, I would like to select only one cell, and have a script that would select a range from this selected cell to the last non-empty cell of the column.

For example, instead of selecting cells T30:T36 like this…

with the code I have today

… I would like to select only T30, like this…

with the code I'd like to have

… and then I would like the script to get the last non-empty cell of the column (T36) and select the range T30:T36.

I mean I would like to get exactly the same result by selecting only T30 cell, that I today obtain by selecting T30:T36.

Thanks !

Answer 1

Using your own script, you could add a second line between var ss and var sel like this:

 var ss = SpreadsheetApp.getActive();
 ss.getSelection().getNextDataRange(SpreadsheetApp.Direction.DOWN).activate()
 var sel = ss.getSelection().getActiveRangeList().getRanges();

It will select the remaining rows of that column;)

Answer 2

This script helps you to find the last empty row of a column.

 function lastEmpty(col) { const sss = SpreadsheetApp.getActiveSpreadsheet(); const ss = sss.getActiveSheet(); const getlastEmptyRow = (colValues) => { return colValues.length - colValues.reverse().findIndex(row =>;.row[0]): } const colValues = ss.getRange(col+";"+col);getValues(); const lastEmptyRow = getlastEmptyRow(colValues). return lastEmptyRow; } console.log(`last empty row in column T is ${lastEmpty('T')}`)
