Can I convert the other way, from commas to semicolons?

Yes. Choose ; as the separator under Download. That's what Excel in a European locale opens correctly with a double-click.

Why not just use Find & Replace?

Because commas already inside values become new columns, and every row after the first one with a comma in the text is shifted. A converter has to parse the file first and quote those values.

Is my file uploaded anywhere?

No. The file is read, checked and fixed in your browser. For a paid download only the row count, the platform and a fingerprint of the file (SHA-256) are sent, so you aren't charged twice for the same file.

How much does it cost?

Checking a file and previewing the fixes is free. Downloading the fixed file is free up to 50 rows. A larger file costs 1 credit, and for 24 hours you can download the same file again in another format or encoding at no extra cost. No subscription needed; agencies that fix files every month can choose Pro: 300 files a month for $19.

Convert a semicolon CSV to a comma CSV

Excel uses your Windows list separator when it saves a CSV, and in much of Europe that's a semicolon. Drop the file below and download it with commas: the tool quotes values that contain a comma, removes Excel's sep=; line and, if you want, converts decimal commas too.

Why it happens

CSV has no single standard separator. Excel takes it from the Windows regional settings: where the decimal separator is a comma (Germany, Poland, Czechia, France, the Netherlands and many others), the list separator is a semicolon, so Excel's "CSV" is really semicolon-separated.

Importers that expect commas, such as Shopify, WooCommerce and most web apps, then read each row as one long column. Replacing every ; with , doesn't work either: commas inside values ("Warm, soft hat" or 24,90) turn into extra columns.

How to fix it manually

Google Sheets

File → Import → Upload, and choose Semicolon as the separator type.
File → Download → Comma-separated values (.csv). Sheets always writes commas and UTF-8.

LibreOffice Calc

Open the file and tick Semicolon as the separator.
File → Save As → Text CSV, tick "Edit filter settings" and choose , as the field delimiter.

Windows (affects every program)

Control Panel → Region → Additional settings → List separator: change ; to ,.

Before and after

Before

Name;Price;Description
Wool beanie;24,90;Warm, soft hat

After

Name,Price,Description
Wool beanie,24.90,"Warm, soft hat"

The description contains a comma, so it gets quotes. The price becomes 24.90 only if you switch on number conversion.

Fix it automatically

Detects the separator: semicolon, tab or |.
Writes commas and puts quotes around values that contain one.
Removes Excel's sep=; line.
Converts decimal commas (24,90 → 24.90) on request. It's off by default, because some importers want them.
Saves as UTF-8, with a BOM if the file will be opened in Excel.

Checking and the preview are free. Downloads are free up to 50 rows; a larger file costs 1 credit.

Choose a file

The file is read and repaired inside your browser. Nothing is uploaded: only the row count and the platform are ever sent to us, so supplier prices and customer data stay private.
