function fillValuesDown() {
  var spreadsheet = SpreadsheetApp.getActive()
  var currentRange = spreadsheet.getRange("A2:A" + spreadsheet.getLastRow())
  var newRange = []
  var newFillValue
  currentRange.getValues().map(function(value) {
    if (value[0] !== '') {
      newFillValue = value[0]
      newRange.push([newFillValue])
    } else {
      newRange.push([newFillValue])
    }
  })
  currentRange.setValues(newRange)
}

helpful, thankyou!

hey ! Thanks for this coding. You have resolved my problems of fill cell with Coding & Macros.
can you please tell me if i want to autofill the B & D also along with we're doing with A in your coding
spreadsheet.getRange("A2:A" + spreadsheet.getLastRow())
Please tell me it will help me...

Thank you!!

Thank you!!

You're welcome!

Very nice @al-codaio
Is there an easy way to turnaround the functionality? In my sheets I need the value from a lower cell instead of the cell above.

Unfortunately it would require a bit of editing to the loop that goes through all the cells in currentRange, would love for someone to figure it out!

How would this coding change if you wanted consistent text to be entered into any blank cell as the macro runs?

You could have to change up the if statement starting in row 12. You'll have to figure out a way to tell the script when to stop because it will just continue filling empty cells until the bottom of the sheet.
