Frequently Asked Questions
How do I convert Excel to CSV?
Open the Excel file in the browser-based converter or use Python's openpyxl library. Select the sheet you want to export, choose UTF-8 encoding, and download the resulting CSV file. In Excel itself, File → Save As → CSV UTF-8 exports the active sheet.
How do I export a specific Excel sheet as CSV?
In a converter tool, upload the XLSX file and select the sheet name from the dropdown before exporting. In Python with openpyxl, access the sheet by name with `wb['Sheet1']` and write its rows using the csv module.
Does Excel to CSV lose formatting?
Yes. CSV stores only cell values — no fonts, colors, formulas, merged cells, or charts. Numeric formats (dates, currencies, percentages) are exported as their displayed string values. Formula results are exported as the calculated value, not the formula.
How do I handle commas in Excel cells when converting to CSV?
Any cell value containing a comma is automatically quoted with double quotes in the CSV output. This is part of the CSV standard (RFC 4180). A proper CSV writer handles this transparently; never do a naive tab/comma replace manually.
How do I batch convert Excel files to CSV?
Use Python with openpyxl or pandas in a loop. Iterate over all XLSX files in a directory with `glob.glob('*.xlsx')`, read each with `pd.read_excel()`, and write each sheet with `df.to_csv()`. This handles hundreds of files in seconds.
