📊 CSV Viewer

Yes. The CSV Viewer in Yioo Tools is a 100% client-side tool that uses only your computer resources. Uploaded files and the data parsed into the table are not sent to any external server or database, so you can use it safely.

There is no fixed file-size limit enforced by the tool, but because it runs in the browser, it is optimized for comfortable use with files up to several dozen megabytes. Very large files in the hundreds of megabytes may cause browser delays or temporary freezes depending on your device.

Yes. The main search box still filters all rows quickly. You can also open the filter and column extract panel to filter by a specific column condition, show only selected columns, and copy or download the current filtered result as CSV.

Use it when you need to inspect, search, and sort a CSV file without opening a spreadsheet application.
