String replacement in excel using Python

Question

I want to remove % and replace with a string, and to remove space and replace it with under score.

This is what I have done so far:

# Open Excel file from a user imput
import xlrd, xlwt
filename = raw_input("Enter Excel file name with extension (.xls) and path")
oldbook = xlrd.open_workbook(filename)
newbook = xlwt.Workbook()

# For all the sheets in the workbook
for sheetname in oldbook.sheet_names():
    oldsheet = oldbook.sheet_by_name(sheetname)
    newsheet = newbook.add_sheet(sheetname)

    # For all the rows and all the columns in an excel
    for ii in range(oldsheet.nrows):
        for jj in range(oldsheet.ncols):
            # Replace
            range.replace("%", "Perc")

# Save the file in a desired location with the desired name
savelocation = raw_input("Enter a new path and file name with extension (.xls) to save the new Excel spread sheet ")
newbook.save(savelocation)

Answer 1

One advice, read cell data into a string and then manipulate it.

Try this: (Unfortunately I cannot run it at the moment)

# Open Excel file from a user imput
import xlrd, xlwt
filename = raw_input("Enter Excel file name with extension (.xls) and path")
oldbook = xlrd.open_workbook(filename)
newbook = xlwt.Workbook()

# For all the sheets in the workbook
for sheetname in oldbook.sheet_names():
    oldsheet = oldbook.sheet_by_name(sheetname)
    newsheet = newbook.add_sheet(sheetname)

    # For all the rows and all the columns in an excel
    for ii in range(oldsheet.nrows):
        for jj in range(oldsheet.ncols):
            # Replace
            CellString=str(oldsheet.cell(ii, jj).Value)
            CellString=CellString.replace("%", "Perc")
            CellString=CellString.replace(" ", "_")
            newsheet.write(ii, jj, CellString)
# Save the file in a desired location with the desired name
savelocation = raw_input("Enter a new path and file name with extension (.xls) to save the new Excel spread sheet ")
newbook.save(savelocation)
