Frequently Asked Questions
What is CSV?
CSV stands for Comma-Separated Values. It is a plain-text format where each line represents a row of data and values within a row are separated by a delimiter such as a comma, semicolon, or tab.
What is the difference between CSV and JSON?
CSV is a flat, tabular format ideal for spreadsheets. JSON is a hierarchical, key-value format used in APIs and web applications. Converting CSV to JSON makes tabular data easier to use in code.
Can I use a header row?
Yes. When the header row option is enabled, the first row of your CSV is used as object keys, producing an array of objects. When disabled, the output is an array of arrays.
What delimiter formats are supported?
This tool supports comma, semicolon, tab, and custom delimiters. Choose the one that matches your CSV data.
Does this tool store my data?
No. All processing happens in your browser. Your CSV data is never sent to any server.
