Google 表格随机复制并使用脚本排序

Question

What I'm attempting to do is copy a column over and re-sort it. Problem is, it captures all available cells and uses the same space to re-sort, causing blank spaces. The idea is to create tournament match pairings, with the first column being the Roster itself, and following columns being players they will be matched against.

I'd also like to add a line that verifies a name doesn't appear twice on the same row, reshuffling until the column is all unique along each row

This is the code I have so far. I attempted to filter the data by swapping

  range2.setValues(shuffleArray(range.getValues()));

for

  range2.setValues(shuffleArray(range.getValues().filter(String)));

but this results in a "Number of data rows is 10 when range is 41" error, not verbatim obviously. I'm trying to collapse the blank spaces that are shown in this Screenshot .

I'm sure I can figure out how to expand it by however many matches I wish to generate.

function shuffleRange() {
  var sheet = SpreadsheetApp.getActive().getSheetByName('SETUP');
  var range = sheet.getRange('A31:A')
  var range2 = sheet.getRange('C31:C');
  range2.clearContents;
  range2.setValues(shuffleArray(range.getValues()));
}

function shuffleArray(array) {
  var i, j, temp;
  for (i = array.length - 1; i > 0; i--) {
    j = Math.floor(Math.random() * (i+1));
    temp = array[i];
    array[i] = array[j];
    array[j] = temp;
  }
  return array;
}

EDIT::::: Code has been moved to a test sheet hence different name and ranges, ive adjusted the samples when i moved them of course

function shuffleRange() {
  var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet4');
  var range = sheet.getRange('A1:A40')
  var v = range.getValues().filter(String);      
        
      //Match 1
  var values = shuffleArray1(v);
  while (v.length != [...new Set(values.map(([a]) => a))].length) {
    values = shuffleArray1(v);  
  }
  range.offset(0, 1, values.length).setValues(values);

      //Match 2
  var values2 = shuffleArray2(v);
  while (v.length != [...new Set(values2.map(([a]) => a))].length) {
    values = shuffleArray2(v);  
  }
  range.offset(0, 2, values.length).setValues(values2);
}

function shuffleArray1(array) {
  var i, j, temp;
  for (i = array.length - 1; i > 0; i--) {
    j = Math.floor(Math.random() * (i+1));
    temp = array[i];
    array[i] = array[j];
    array[j] = temp;
  }
  return array;
}

function shuffleArray2(array) {
  var u, v, temp;
  for (u = array.length - 3; u > 0; u--) {
    v = Math.floor(Math.random() * (u+2));
    temp = array[u];
    array[u] = array[v];
    array[v] = temp;
  }
  return array;
}

Modification points:

• I think that range2.clearContents might be range2.clearContent() .
• In your script, by sheet.getRange('A31:A') , all rows in the sheet are retrieved.

When these points are reflected in your script, how about modifying shuffleRange() as follows?

Modified script:

function shuffleRange() {
  var sheet = SpreadsheetApp.getActive().getSheetByName('SETUP');
  var lastRow = sheet.getLastRow();
  var range = sheet.getRange('A31:A' + lastRow);
  var range2 = sheet.getRange('C31:C' + lastRow);
  range2.clearContent();
  var values = shuffleArray(range.getValues()).filter(String);
  range.offset(0, 2, values.length).setValues(values);
}

• I'm not sure about the last row of your sheet. So, I proposed the above modification.

Added 1:

From your following new question,

essentially if the row contains a duplicate it has to reshuffle until each row contains a unique name from the original column, to create unique match pairings for tournaments, this will check the whole row, as some tournaments run only 2 matches, some up to 21

In this case, how about the following sample script?

Sample script:

function shuffleRange() {
  var sheet = SpreadsheetApp.getActive().getSheetByName('SETUP');
  var lastRow = sheet.getLastRow();
  var range = sheet.getRange('A31:A' + lastRow);
  var range2 = sheet.getRange('C31:C' + lastRow);
  range2.clearContent();
  var v = range.getValues().filter(String);
  var values = shuffleArray(v);
  while (v.length != [...new Set(values.map(([a]) => a))].length) {
    values = shuffleArray(v);
  }
  range.offset(0, 2, values.length).setValues(values);
}

• In this case, when the duplicated values are included in values , shuffleArray function is run again.

From your following reply,

Unfortunately it produced duplicate lines almost immediately once i duplicate the functions to create a second set of results

I added a new sample so you can see how im trying to expand it across several columns of results, this will create a set number of matches. I will, when done, swap the counter for a cell check so a user can set the match number, but thats later

Sample script:

function shuffleRange() {
  var sheet = SpreadsheetApp.getActive().getSheetByName('SETUP');
  var range = sheet.getRange('A1:A40');
  var v = range.getValues().filter(String);

  var createValues = v => {
    SpreadsheetApp.flush(); // I'm not sure whether this line is required.
    var temp = sheet.getRange(1, 1, 40, sheet.getLastColumn()).getValues();
    var existValues = temp[0].map((_, c) => temp.map(r => r[c]).join("")).filter(String);
    var values;
    do {
      values = shuffleArray1(v);
      while (v.length != [...new Set(values.map(([a]) => a))].length) {
        values = shuffleArray1(v);
      }
      var check = values.map(([a]) => a).join("");
    } while (existValues.some(e => e == check));
    return values;
  }

  var values1 = createValues(v);
  range.offset(0, 1, values1.length).setValues(values1);

  var values2 = createValues(v);
  range.offset(0, 2, values2.length).setValues(values2);
}

• In this modification, the new column values are created by checking all existing columns.

Adding to Tanaike's suggestion I've joined your two functions in order to be able to re-shuffle. I'm not as well-versed in coding, and probably there's a more-alike version of your code that also enables the re-shuffling. But you can try this:

 function shuffleRange() {
  var sheet = SpreadsheetApp.getActive().getSheetByName('SETUP');
  var lastRow = sheet.getLastRow()
  var range = sheet.getRange('A31:A' + lastRow);
  var range2 = sheet.getRange('C31:C' + lastRow);
  range2.clearContents;
      function shuffleArray() {
        var i, j, temp;
        var array = range.getValues()
        var array2 = range.getValues()
        var count= 1;
        while (count>0){
          count=0
          for(i=array.length-1;i>0;i--){
            j = Math.floor(Math.random() * (i+1));
            temp = array2[i];
            array2[i] = array2[j];
            array2[j] = temp;
          }

            for(i=0;i<array.length;i++){
             if(array[i].toString() == (array2[i]).toString()){count = count+1}
            }}
        return array2
      }

  range2.setValues(shuffleArray())
}

I've make it try tenths of times and never got a duplicate:
