Google Spreadsheets - Resetting cells while keeping mathematical functions?

Question

I am working in Google Spreadsheets and I am wanting to create a button that, when activated, will reset the data in a range of cells but keep any math functions assigned to those cells.

I have experimented with the basic clearContent(); scripting but I found that this deletes all data within a cell (text and functions).

Is there a way to keep the functions while just clearing the text?

Solution 1

There is a good reason to want to delete the data from a cell and keep the formula. I have created sheets that accomplish computational tasks my principal wants. The structure requiored I make the workbook page for a week at a time. If I copy the sheet for the next week, then delete the data, I am all set for the next week. As I input data the formulas are used to compute the new calculations. Excel has a CLEAR button which allows this to be done. Select the cells to delete the data and remove it while leaving the formulas.

There is no function to do what you ask - and for good reason.

A spreadsheet formula exists to calculate the value of a cell or range of cells.

If you clear the value currently in a cell, but keep the formula, then the value will be recalculated... and you'll have a value displayed again.

So it makes sense that if you want a cell's value cleared, you also want it's formula cleared, so Range.clearContent() does both.

If you really, really, really want to do this, though, it's a three-liner (without error checking).

function clearValues(range) {
  var formulas = range.getFormulas();
  range.clearContent();
  range.setFormulas(formulas);
}

I know this is an old post; for others that want to delete a range of data using Google Apps Script in your spreadsheet yet want to retain your formula, try the following.

 var sheet = SpreadsheetApp.getActive().getSheetByName('YourSheetName');
 sheet.getRange('G2:G1000').clear({commentsOnly: true});

Use case... My Menu clears two columns of data (A and G). Column "A" contains a user entered "X" in some cases. Column "G" has a formula that looks for the value in row/column "A" If the cell is changed to contain an "X" then the formula inserts the current date in row/column "G".
