Your CSV is broken.

When you double-click a CSV file and Excel shows gibberish, one long column, or an error — it's almost always one of three things:

1. The file uses a different column separator than Excel expects
2. There's an invisible character at the start making the first column unreadable
3. The file was saved in a different text format, so special characters show up as garbage

You don't need to know which one. Drop the file above — we detect and fix it in one click.

This is the most common CSV problem. All your data is crammed into column A.

It happens because the file uses semicolons or tabs instead of commas, and your version of Excel doesn't know how to split them.

The usual fix: Data → Text to Columns → choose the right separator. Or just drop the file here and we'll convert it automatically.

Seeing ä instead of ä? That means the file was saved in one text format but opened in another.

This is extremely common with files from European or Asian systems. Customer names, addresses, product descriptions — any text with accents gets scrambled.

Drop the file here. We detect the correct format and convert everything so it displays properly.

The manual way: open in Notepad, search Google, try five things, give up and ask IT.

The fast way: drop the file here. We run it through 14 checks — columns, text format, invisible characters, empty rows, duplicates — and fix everything in one click. Done in a couple of seconds.
