Count blank rows on sheets

This project includes two scripts:

• Count blank rows on a given sheet: Traverses the used range on a given worksheet and returns a blank row count.
• Count blank rows on all sheets: Traverses the used range on all of the worksheets and returns a blank row count.

Note

For your script, a blank row is any row where there's no data. The row can have formatting.

This sheet returns count of 4 blank rows

This sheet returns count of 0 blank rows (all rows have some data)

Sample code: Count blank rows on a given sheet

function main(workbook: ExcelScript.Workbook): number
{
  // Get the worksheet named "Sheet1".
  const sheet = workbook.getWorksheet('Sheet1'); 
  
  // Get the entire data range.
  const range = sheet.getUsedRange(true);

  // If the used range is empty, end the script.
  if (!range) {
    console.log(`No data on this sheet.`);
    return;
  }
  
  // Log the address of the used range.
  console.log(`Used range for the worksheet: ${range.getAddress()}`);
    
  // Look through the values in the range for blank rows.
  const values = range.getValues();
  let emptyRows = 0;
  for (let row of values) {
    let emptyRow = true;
    
    // Look at every cell in the row for one with a value.
    for (let cell of row) {
      if (cell.toString().length > 0) {
        emptyRow = false
      }
    }

    // If no cell had a value, the row is empty.
    if (emptyRow) {
      emptyRows++;
    }
  }

  // Log the number of empty rows.
  console.log(`Total empty rows: ${emptyRows}`);

  // Return the number of empty rows for use in a Power Automate flow.
  return emptyRows;
}

Sample code: Count blank rows on all sheets

function main(workbook: ExcelScript.Workbook): number
{
  // Loop through every worksheet in the workbook.
  const sheets = workbook.getWorksheets();
  let emptyRows = 0;
  for (let sheet of sheets) {     
    // Get the entire data range.
    const range = sheet.getUsedRange(true);
  
    // If the used range is empty, skip to the next worksheet.
    if (!range) {
      console.log(`No data on this sheet.`);
      continue;
    }
    
    // Log the address of the used range.
    console.log(`Used range for the worksheet: ${range.getAddress()}`);
      
    // Look through the values in the range for blank rows.
    const values = range.getValues();
    for (let row of values) {
      let emptyRow = true;
      
      // Look at every cell in the row for one with a value.
      for (let cell of row) {
        if (cell.toString().length > 0) {
          emptyRow = false
        }
      }
  
      // If no cell had a value, the row is empty.
      if (emptyRow) {
        emptyRows++;
      }
    }
  }

  // Log the number of empty rows.
  console.log(`Total empty rows: ${emptyRows}`);

  // Return the number of empty rows for use in a Power Automate flow.
  return emptyRows;
