    Converting .xlsx files to .csv in Python is straightforward with the right libraries. CSV files are lightweight, widely supported, and ideal for data processing pipelines, while Excel files often require additional parsing. Below are the most efficient methods to achieve this.

    Pandas Library

    Steps:

    • Install dependencies

    pip install pandas openpyxl
    Copied!

    • Read the Excel file and export to CSV

    import pandas as pd

    # Load Excel file
    df = pd.read_excel("input.xlsx", sheet_name="Sheet1")

    # Save as CSV without index column
    df.to_csv("output.csv", index=False, encoding="utf-8-sig")
    Copied!

    • For multiple sheets

    all_sheets = pd.read_excel("input.xlsx", sheet_name=None)
    for sheet_name, data in all_sheets.items():
    data.to_csv(f"{sheet_name}.csv", index=False, encoding="utf-8-sig")
    Copied!

    Why use Pandas?

    • Handles large datasets efficiently.

    • Supports cleaning and preprocessing before export.

    • Works seamlessly with multiple sheets and encodings.

    openpyxl + csv Module

    Steps:

    • Install openpyxl

    pip install openpyxl
    Copied!
