Will my Excel formulas be kept in the CSV?

No. CSV stores only the resulting values as plain text — formulas, formatting, colours, charts and multiple sheets are not included. It is meant for raw data exchange, not for keeping a live workbook.

Which sheet gets converted if my Excel file has several?

The first (active) sheet is exported, because a CSV file holds a single flat table. If you need every sheet, split them into separate workbooks first and convert each one.

What delimiter and text encoding does the CSV use?

Values are comma-separated and saved as UTF-8, and any value that contains a comma or line break is wrapped in quotes, so the file imports cleanly into databases and spreadsheets without garbled characters or shifted columns.

Will leading zeros and long numbers survive?

The CSV stores exactly what is in each cell, including leading zeros in ZIP codes or IDs. Whether they are preserved on re-import depends on how the receiving app types the column, so import them as text if it matters.

Why convert Excel to CSV?

CSV is the universal, lightweight format for importing data into databases, scripts, analytics tools, e-commerce and CRM systems, and other apps that cannot read the .xlsx format directly.

Is there a row or file-size limit?

Large sheets with tens of thousands of rows convert fine, and because all formatting, formulas and styling are dropped, the resulting CSV is usually far smaller and faster to load than the original workbook.

Do I need Excel installed to convert?

No. The conversion runs on the server, so you only need a browser — it works the same on Windows, Mac, Linux, a phone or a Chromebook without Excel or any add-in.
