Before finding the reasons that make this conversion crucial, let’s look at the difference between these two common Excel file formats.
XML | XLSX |
Extensible Markup Language is a format for plain-text-based files. | MS Excel spreadsheet format used from 2007 and later versions. |
Organize data in a structured and hierarchical format. | Stores structured and complex data in rows and columns |
Users need tags to define the information within the file. | Offers basic to advanced formatting for analysis, data sorting, and reports. |
Used by applications and OS to exchange information and save configuration settings. | Accessible on multiple applications (MS Excel/Google Sheets/Libre Office), OS, and even mobile phones. |
With a clear understanding of the formats, check out these major factors for which users convert XML to XLSX:
There are a few manual processes to save XML as an XLSX file and an automated tool that makes the process a bit quicker and simpler. Let’s go through each one of them briefly by following the steps below.
There are two different processes that you can use here. One is for everyone by using MS Excel, and another one is basically for techies who have programming knowledge. These are:
Note: Using this process, you can even convert XML to CSV.
This method is for sure direct and from within the Excel application. It is suited for the small XML to XLSX conversion, but for bulk datasets, Excel may freeze. Also, there is a potential risk that formatting errors occur since no advanced formatting options are available. This can even lead to crashes. So, it’s better to look at other alternatives.
There is a unique challenge that most users face during this conversion: “Why Excel won’t open XML file?” And due to this, you cannot save to XLSX either. One major factor for this is that XML files over 100 MB in Excel cause crashes. So, to perform a smooth conversion here, we prefer Python scripting that you can try too. It parses XML and directly gives output in XLSX. Use the following code:
#First, Import Libraries import xml.etree.ElementTree as ET from openpyxl import Workbook Import pandas as pd # Then, Load XML tree = ET.parse(‘largefile.xml’) root = tree.getroot() # Now, Create a New Excel Workbook wb = Workbook() data = wb.active ws.title = “XML File Data” # Further, Extract Column Names from First Element headers = [child.tag for child in root[0]] data.append(headers) # Also, Extract Data Rows for item in root: row = [child.text for child in item] data.append(row) # Finally, Save to XLSX wb.save(‘output.xlsx’) OR df = pd.DataFrame(data) df.to_excel(“output.xlsx”, index=False) |

Drawbacks:
Though online tools would have done this task too but they lack security. Therefore, we introduce you to the SysInfo XML Converter Tool, a reliable and advanced utility with some special filters and features. It makes the process speedy with full accuracy, ensuring folder structure is maintained and the integrity is retained. Additionally, the tool can handle multiple XML datasets at once and works efficiently on all Windows OS versions.
Besides this, download the demo version of the tool. Use it to convert upto 1 MB of XML file to XLSX or other formats for free. Moreover, take a look at this user case, where the tool proved to be helpful:
“The finance team received 5,000+ XML invoices monthly from different vendors. Instead of opening each file manually, they used the XML to XLSX Converter. It transformed all XML files into a single consolidated XLSX report within a few hours, saving time and effort.”
Steps to Convert XML File to XLSX
To sum up, in this blog, we learned three different ways to convert XML to XLSX for free and with a tool. Converting the file formats here isn’t just about the change of extensions, but also about making data more accessible, usable, and scalable. Moreover, in business needs, choosing the optimum solution like a professional tool can be of great help.
Ans- To do so, you need to change the XML file to XLSX. For that, using an expert tool like the XML File Converter is a reliable choice. It is quick, secure, keeps data intact, and handles bulk conversions without any limitations or difficulties.
Ans- No, the file formats are both represented by MS Excel, but they differ in properties and use. XML is a more structured, coded, and plain-text format. Whereas XLSX is generally used for analysis, data filtering, creating reports, and more.
