How to Convert Excel to CSV

Excel is brilliant for working with numbers, but the .xlsx file it saves is not always what other software wants. Import a spreadsheet into a database, an email marketing tool, an accounting system or a coding script, and nine times out of ten it asks for a CSV instead. This guide explains what CSV is, when you need it, and how to convert an Excel file to CSV online in a few seconds — without losing a single row.

What is a CSV file?

CSV stands for Comma-Separated Values. It is the simplest possible way to store a table: plain text, one row per line, with each cell separated by a comma. Open a CSV in a text editor and you would see something like this:

name,email,plan
Ada Lovelace,ada@example.com,Pro
Alan Turing,alan@example.com,Free

Because it is just text, a CSV has no formulas, no colours, no fonts and no multiple sheets — only the raw data. That sounds like a limitation, but it is exactly why CSV is the universal language for moving data between programs.

Why convert Excel to CSV?

• Importing into other systems. CRMs, databases (MySQL, PostgreSQL), mailing-list tools and e-commerce platforms almost all accept CSV uploads.
• Feeding scripts and code. Python, R and virtually every programming language read CSV out of the box, making it the default for data analysis.
• Universal compatibility. A CSV opens on any device with any spreadsheet app — no Excel licence required.
• Smaller, cleaner files. Stripping out styling leaves a tiny file that is easy to share and version-control.

Convert Excel to CSV, step by step

1. Open the converter. Go to the Excel to CSV tool and drop in your .xlsx or .xls file.
2. Convert. The first sheet is read and every cell is written out as comma-separated text.
3. Download your .csv, ready to import anywhere.

Things to check before you convert

A CSV can only hold flat, tabular data, so a couple of quick checks in Excel save you headaches later:

• One sheet at a time. A CSV holds a single table. If your workbook has several sheets, convert the one you need (or export each separately).
• Formulas become values. A cell showing =A1+B1 is saved as its result, not the formula — usually exactly what you want.
• Keep a clean header row. Put column names in the first row and avoid merged cells, which do not translate to plain text.
• Watch numbers with leading zeros. Codes like 00123 may lose their zeros; format those columns as text in Excel first if the zeros matter.

What about commas inside my data?

Good question — if a cell already contains a comma (say, Smith, John), a naive export would break the columns. The CSV standard handles this by wrapping such values in double quotes: "Smith, John". A proper converter does this automatically, so addresses, notes and full names stay in one piece.

Going the other way — and beyond

Need to turn a CSV back into a formatted spreadsheet? Use CSV to Excel to rebuild an .xlsx. If you are feeding data to a web app or API, CSV to JSON may be a better fit. And when you just need a shareable, print-ready copy of the sheet, Excel to PDF locks the layout for everyone.

Is it private and free?

Converting a spreadsheet reliably needs proper office software, so the tool runs on our secure server. Your file travels over an encrypted HTTPS connection, is converted in an isolated workspace, and is deleted automatically the moment the CSV is returned — nothing is stored, logged or shared. It is completely free, with no watermark, no row limit tricks and no account required.

Frequently asked questions

Does it work with old .xls files? Yes — both the modern .xlsx and the legacy .xls format are supported.

Will my formulas be included? Formulas are converted to their calculated values, since CSV cannot store live formulas.

Which sheet gets exported? The first (active) sheet of the workbook. To export another, move it first or convert your workbook one sheet at a time.

Will special characters and accents survive? Yes. The file is saved in UTF-8, so names and symbols from any language come through correctly.
