How to convert an Excel document to XML format?

This recipe helps you convert an Excel document to XML format

Recipe Objective

In big data scenarios, converting data from Excel format to XML format using Python can be used to to exchange data between different applications. We process complex XML files into a relational format or a Big Data format such as Parquet/ORC . XML is user-readable and more commonly used in network communication, especially with the rise of REST-based web services. The tools needed to manage big data analytics, often in the form of NoSQL databases, only map over to XML in a partial sense. XML is considered to be at odds with relational schemas, which puts it in a camp with most of NoSQL technology

System requirements :

Install Yattag python module as follows: pip install yattag
Install OpenPyXL python module as follows:pip install openpyxl
The below codes can be run in Jupyter notebook , or any python console
In this example we are going to use the excel employee dataset

Step 1: Import the modules


import openpyxl
import yattag  
import load_workbook
import Doc, indent

Step 2: Load the Workbook

create a Yattag document using yattag module and load the workbook and the worksheet.


#load the excel file along with path where exists
wb = load_workbook("empdata.xlsx")
ws = wb.worksheets[0]

# Create Yattag doc, tag and text objects
doc, tag, text = Doc().tagtext()

Step 3: Fill the headers with Yattags

Fill the headers with Yattags asis() method which enables us to input any string as the next line



xml_header = ''
xml_schema = ''

doc.asis(xml_header)
doc.asis(xml_schema)

Step 4: Then create main Tag

create main tag Employees as below:


with tag('Employees'):

Step 5: Now start loop through the sheet

Now start loopthrough the sheet with the iter_rows method. The iter_rows method returns a generator with all the cells. We use a list comprehension to get all the values from the cells.


for row in ws.iter_rows(min_row=2, max_row=100, min_col=1, max_col=12):
        row = [cell.value for cell in row]
        with tag("Employee"):
            with tag("FirstName"):
                text(row[0])
            with tag("LastName"):
                text(row[1])
            with tag("Email"):
                text(row[10])
            with tag("Phone"):
                text(row[8])
            with tag("Company"):
                text(row[2])

Step 6: Adding the Yattag indent

Next, we are adding the Employees. When finished we indent our result with Yattags indent method.


 result = indent(
    doc.getvalue(),
    indentation = '    ',
    indent_text = True
)
print(result)
with open("employee1.xml", "w") as f:
    f.write(result)

The complete code looks as follows :


import openpyxl, yattag  
from openpyxl import load_workbook
from yattag import Doc, indent

wb = load_workbook("empdata.xlsx")
ws = wb.worksheets[0]

# Create Yattag doc, tag and text objects
doc, tag, text = Doc().tagtext()

xml_header = ''
xml_schema = ''

doc.asis(xml_header)
doc.asis(xml_schema)

with tag('Employees'):
    # Use ws.max_row for all rows
    for row in ws.iter_rows(min_row=2, max_row=100, min_col=1, max_col=12):
        row = [cell.value for cell in row]
        with tag("Employee"):
            with tag("FirstName"):
                text(row[0])
            with tag("LastName"):
                text(row[1])
            with tag("Email"):
                text(row[10])
            with tag("Phone"):
                text(row[8])
            with tag("Company"):
                text(row[2])

result = indent(
    doc.getvalue(),
    indentation = '    ',
    indent_text = True
)
print(result)

with open("employee.xml", "w") as f: #give path where you want to create
    f.write(result)

Output of the above Code as follows :
