Frequently Asked Questions

Are CSV tools free?

Yes, all CSV tools are free. Convert to Excel, JSON, PDF, SQL, XML, Markdown, merge, split, sort, filter, view, and more without registration or payment. All processing happens in your browser.

Do CSV files get uploaded?

No. All CSV processing is done entirely in your browser. Your files never leave your device. We never see, store, or transmit your data.

What CSV options are supported?

Tools support common delimiters (comma, semicolon, tab, pipe), encoding (UTF-8, Windows-1252, ISO-8859-1), and first row as header where applicable. Many tools auto-detect delimiter and encoding.

Can I merge multiple CSV files?

Yes, use our CSV Merge tool to combine multiple CSV files with optional first-row-as-header handling. The tool runs in your browser and keeps your data private.

Is there a file size limit?

Limits depend on your device's memory. Very large files (e.g., millions of rows) may take longer. For best results, we recommend files under 50MB for most tools.
