When to use it

  1. Use it when you need to pull only the rows containing a specific value out of logs or sales data with hundreds of thousands of rows.

  2. When a file is too big to open or exceeds Excel's 1,048,576-row limit, you can parse the large CSV right in your browser.

  3. When Korean text from EUC-KR encoded CSVs saved in Korean versions of Excel shows up garbled, switching the encoding option fixes it instantly.

  4. Since your data never leaves your browser, you can safely process files containing customer information or internal data.
