I have a spreadsheet with lots of data and formulae. I am importing a particular cell value from spreadsheet into the google script. However since the cell is not updated with a recent revision, the script is taking the previous value. For now I have given "sleep" in script to temporarily stop the script from running so as to wait for the spreadsheet to get updated. I am not sure if the time that gave in sleep is sufficient in future with the data in spreadsheet increasing continuously.
I would like to know if there is a way to check the status of spreadsheet (updated? updating? etc). I will only run the script when the spreadsheet is updated.
Any help will be highly appreciated. This is the last issue that I reckon could be to finish my task after being struggled in logic, code, triggers etc.
As Anees mentioned in the comments, the flush() command is what you are looking for.
SpreadsheetApp.flush();
