XML to XLSX Converter and Data Merger

This Python script is designed to convert XML files to XLSX format and merge data from multiple XLSX files into a single file.

Features

• XML to XLSX Conversion: Converts XML files to XLSX format while preserving XML attributes.
• Data Merging: Merges data from multiple XLSX files based on specified columns.
• Automatic Chunking: Splits merged data into smaller chunks if the size exceeds a specified limit.

Requirements

• Python 3.x
• xml.etree.ElementTree module
• openpyxl library
• pandas library

Usage

XML to XLSX Conversion

from xml_to_xlsx import xml_folder_to_xlsx

# Specify the folder containing XML files and the folder to save XLSX files
xml_folder = "path/to/xml_folder"
xlsx_folder = "path/to/xlsx_folder"

# Convert XML files to XLSX
xlsx_files = xml_folder_to_xlsx(xml_folder, xlsx_folder)

Data Merging

from data_merger import merge_xlsx_files

# Specify the folder containing XLSX files
folder_path = "path/to/xlsx_folder"

# Merge data from XLSX files
merge_xlsx_files(folder_path)

Folder Structure

• xml_to_xlsx.py: Contains functions for XML to XLSX conversion.
• data_merger.py: Contains functions for merging data from XLSX files.
• test: Example folder containing XML and XLSX files.

How it Works

1. XML to XLSX Conversion: The script parses XML files and extracts attribute data. It then organizes the data into XLSX files, preserving the structure of the XML attributes.

2. Data Merging: The script reads multiple XLSX files, extracts specified columns, and merges them into a single DataFrame. If the merged data exceeds a specified size limit, it automatically splits the data into smaller chunks, each saved as a separate XLSX file.

Limitations

• XML parsing errors may occur if the XML files are not well-formed.
• The script assumes consistent column structures across XLSX files for merging.
