Question

How to divide a google spreadsheet (with about 100 sheets) in two (or more) spreadsheets (of about 50 sheets each) in google-apps-script ?

Alas, due to a google bug (see https://productforums.google.com/d/topic/docs/H2ZakBguOgk/discussion), I can’t copy the entire spreadsheet file and delete some sheets in each spreadsheets.

I can only copy sheets one by one on another spreadsheet, then delete the original sheet(s) if copy is a success.

Thanks in advance 😉

Here is a code snippet that should do what you want, I didn’t test it so maybe you’ll have to tweak some details but the general idea is there…

EDIT : I tested and made the corrections to make it work… sorry for the typos in first version

function splitSS() {
var oldFileID = 'original ss Id'
var newFile = DocsList.getFileById(oldFileID).makeCopy()
var newFileID = newFile.getId()
var ss = SpreadsheetApp.openById(newFileID);
Logger.log(ss.getNumSheets())
var todel = parseInt((ss.getNumSheets())/2);
Logger.log(todel)
var tokeep = ss.getNumSheets()-todel
Logger.log(tokeep)
    for (pa=ss.getNumSheets()-1;pa>tokeep;--pa){ 
      ss.setActiveSheet(ss.getSheets()[pa]);
      var delsheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
      Utilities.sleep(400);
    }
var ssold = SpreadsheetApp.openById(oldFileID);
    for (pa=todel;pa>1;--pa){ 
      ssold.setActiveSheet(ssold.getSheets()[pa]);
      var delsheet = ssold.deleteActiveSheet(); // delete sheets begining with the last one
      Utilities.sleep(400);
    }
}
