Can't write data into Excel-Sheet using openpyxl Workbook

Question

I’m trying to write to specific cells in a Excel-Sheet using openpyxl Workbook. At first I couldn’t write to cells that already had data in them and now I can’t write at all (or I’m just going crazy).

Here’s my code:

    wb = load_workbook("..\..\Decision Tree Classifier  TPS\Decision Tree Classifier  TPS\TestData.xlsx")
    ws1 = wb.get_sheet_by_name("Sheet1")

    #this works
    print(ws1.cell(row=1, column=1).value)

    #these do not
    ws1['D3'] = 5
    ws1.cell(row=5, column=1).value = "SomeValue2"
    ws1.cell(row=7, column=1,value='Hey')
    ws1.cell(row=6, column=1).value = 'TEST'

    wb.save("TestData.xlsx")

I get no errors, the print line works, the write lines do not.

Similar problem here Writing data into Excel-Sheet using openpyxl isn't working, except I have the save function.

What gives?

When you’re saving workbook, provide full path, otherwise you will save it in a Python folder. I’m pretty sure that’s where your Excel workbook with new data resides.

wb.save("..\..\Decision Tree Classifier  TPS\Decision Tree Classifier  TPS\TestData.xlsx")

Also, don’t forget to close your workbook when you’re done with it.

wb.close()

Hope this helps!
