How to write/update data into cells of existing XLSX workbook using xlsxwriter in python

To write or update data into cells of an existing XLSX workbook using the xlsxwriter library in Python, you can follow these steps:

  1. Install the xlsxwriter library if you haven't already:

    pip install XlsxWriter

  2. Import the xlsxwriter library and open the existing workbook using xlsxwriter.Workbook() with the filename of the existing workbook.

  3. Create a worksheet object within the workbook using workbook.add_worksheet() or retrieve an existing worksheet using workbook.get_worksheet_by_name().

  4. Use the worksheet object to write or update data in specific cells using methods like write(), write_string(), write_number(), etc.

  5. Close the workbook to save the changes.

Here's a basic example:

import xlsxwriter # Open an existing workbook workbook = xlsxwriter.Workbook('existing_workbook.xlsx') # Retrieve or create a worksheet worksheet = workbook.get_worksheet_by_name('Sheet1') # Replace 'Sheet1' with the desired sheet name # Write or update data in cells worksheet.write('A1', 'Hello') # Update cell A1 with the text 'Hello' worksheet.write('B1', 'World') # Update cell B1 with the text 'World' worksheet.write('A2', 42) # Update cell A2 with the number 42 # Close the workbook to save the changes workbook.close()

In this example:

  • We open an existing workbook named 'existing_workbook.xlsx'.
  • We retrieve the worksheet named 'Sheet1', but you can change the sheet name as needed.
  • We use the worksheet.write() method to write or update data in specific cells.

Make sure to replace 'existing_workbook.xlsx' and 'Sheet1' with the actual file path and sheet name of your existing workbook. You can also use the write_string(), write_number(), or other appropriate methods to write different types of data.

After running this code, the existing workbook will be updated with the new data in the specified cells.
