Delete Blank Rows and Columns in a Worksheet with Node.js via C++

It is possible to delete all blank rows and columns from a worksheet. This is useful when, for example, generating a PDF file from a Microsoft Excel file and want to convert only rows and columns that contain data or related objects.

Use the following Aspose.Cells methods to delete empty rows and columns:

1. To delete blank rows, use the Cells.deleteBlankRows() method. Please note, for blank rows that will be deleted, it is not only required that Row.isBlank() should be true, but also there should be no visible comment defined for any cell in those rows, and no pivot table whose range intersects with them.
2. To delete blank columns, use the Cells.deleteBlankColumns() method.

Node.js code to delete Blank Rows

const AsposeCells = require("aspose.cells.node");
const path = require("path");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "SampleInput.xlsx");

// Open an existing excel file.
const wb = new AsposeCells.Workbook(filePath);

// Create a Worksheets object with reference to
// The sheets of the Workbook.
const sheets = wb.getWorksheets();

// Get first Worksheet from WorksheetCollection
const sheet = sheets.get(0);

// Delete the Blank Rows from the worksheet
sheet.getCells().deleteBlankRows();

// Save the excel file.
wb.save(path.join(dataDir, "mybook.out.xlsx"));

Node.js code to Delete Blank Columns

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Open an existing excel file.
const workbook = new AsposeCells.Workbook(path.join(dataDir, "SampleInput.xlsx"));

// Create a Worksheets object with reference to the sheets of the Workbook.
const sheets = workbook.getWorksheets();

// Get first Worksheet from WorksheetCollection
const sheet = sheets.get(0);

// Delete the Blank Columns from the worksheet
sheet.getCells().deleteBlankColumns();

// Save the excel file.
workbook.save(path.join(dataDir, "mybook.out.xlsx"));
