Question 1

How does delimiter detection work?

Accepted Answer

The tool analyzes the first several rows of your file, counting occurrences of common delimiters (comma, semicolon, tab, pipe) and checking which one produces consistent column counts across rows. The most likely delimiter is reported with a confidence score.

Question 2

Why can't I open my CSV file correctly in Excel?

Accepted Answer

Excel assumes comma-separated by default, but your file might use a different delimiter like semicolons or tabs. Use this detector to find the actual delimiter, then import the file into Excel using the correct separator in the import wizard.

Question 3

What if my file uses an unusual delimiter?

Accepted Answer

The detector checks for common delimiters (comma, semicolon, tab, pipe) and also attempts to identify custom single-character delimiters. If your file uses something exotic, the tool will show the most likely candidate.

Question 4

Is this the same as a CSV sniffer?

Accepted Answer

Yes. Delimiter detection is sometimes called CSV sniffing. This tool performs the same function as Python's csv.Sniffer class — it examines a sample of the file to determine the delimiter, quoting character, and other formatting details.
