Enter the example value or paste your own input, choose the mode when one is available, and read the first result card for the direct answer. The output area gives a copyable block for code reviews, documentation, API tests, classwork or troubleshooting notes.
What the result means
The first row is treated as a header when the requested column is a name. Numeric input selects a 1-based index.
What is not included
The parser handles quoted cells but does not infer data types or repair malformed CSV.
Privacy note
The calculation runs in your browser. Avoid pasting production secrets, credentials, private keys, customer data or regulated personal data unless your own policy allows browser-based tools.
