Insert row into Excel spreadsheet using openpyxl in Python

Question

I\'m looking for the best approach for inserting a row into a spreadsheet using openpyxl.

Effectively, I have a spreadsheet (Excel 2007) which has a header row, foll

Answer 1

I've written a function which will both insert an entire row anywhere you want in a spreadsheet, or an entire 2D table, with openpyxl.

Every row of the function is explained with a comment but if you want to just insert a single row, just make your row equal to [row]. i.e. if row = [1,2,3,4,5] then set your input to [[1,2,3,4,5]]. If you want this row to be inserted into the top row of your spreadsheet (A1) then Start = [1,1].

You can indeed overwrite the file name as see you can with my example at the bottom.

def InputList(Start, List): #This function is to input an array/list from a input start point; len(Start) must equal 2, where Start = [1,1] is cell 1A. List must be a two dimensional array; if you wish to input a single row then this can be done where len(List) == 1, e.g. List = [[1,2,3,4]]
    x = 0 #Sets up a veriable to go through List columns
    y = 0 #Sets up a veriable to go through List rows
    l = 0 #Sets up a veriable to count addional columns against Start[1] to allow for column reset on each new row
    for row in List: #For every row in List
        l = 0 #Set additonal columns to zero
        for cell in row: #For every cell in row
            ws.cell(row=Start[0], column=Start[1]).value = List[y][x] #Set value for current cell
            x = x + 1 #Move to next data input (List) column
            Start[1] = Start[1] + 1 #Move to next Excel column
            l = l + 1 #Count addional row length
        y = y + 1 #Move to next Excel row
        Start[0] = Start[0] + 1 #Move to next Excel row
        x = 0 #Move back to first column of input data (ready for next row)
        Start[1] = Start[1] - l #Reset Excel column back to orignal start column, ready to write next row

Example with single row being inserted at start of row 7:

from openpyxl import load_workbook
wb = load_workbook('New3.xlsx')
ws = wb.active

def InputList(Start, List): #This function is to input an array/list from a input start point; len(Start) must equal 2, where Start = [1,1] is cell 1A. List must be a two dimensional array; if you wish to input a single row then this can be done where len(List) == 1, e.g. List = [[1,2,3,4]]
    x = 0 #Sets up a veriable to go through List columns
    y = 0 #Sets up a veriable to go through List rows
    l = 0 #Sets up a veriable to count addional columns against Start[1] to allow for column reset on each new row
    for row in List: #For every row in List
        l = 0 #Set additonal columns to zero
        for cell in row: #For every cell in row
            ws.cell(row=Start[0], column=Start[1]).value = List[y][x] #Set value for current cell
            x = x + 1 #Move to next data input (List) column
            Start[1] = Start[1] + 1 #Move to next Excel column
            l = l + 1 #Count addional row length
        y = y + 1 #Move to next Excel row
        Start[0] = Start[0] + 1 #Move to next Excel row
        x = 0 #Move back to first column of input data (ready for next row)
        Start[1] = Start[1] - l #Reset Excel column back to orignal start column, ready to write next row

test = [[1,2,3,4]]
InputList([7,1], test)

wb.save('New3.xlsx')
