Files never leave your device. The Rust engine compiles to WebAssembly and runs entirely in your browser tab.
Open the page, drop your files, download results. No account, no email, no credit card.
No daily caps, no watermarks, no quality limits. The engine runs on your hardware, so it costs nothing to operate.
The entire engine, CLI, and web app are MIT licensed. Inspect the code, verify the operations, or contribute.
Remove empty rows, trim whitespace, and deduplicate entries without writing a single formula. bnto applies consistent cleaning rules across every row.
Rename headers, reorder columns, and transform values in bulk. Changes apply to the entire file at once, so you never miss a row.
Convert CSV to JSON and back. Merge multiple CSV files into one. Standardize column names across datasets before combining them.
Every feature is designed around how people actually work: batch processing, format flexibility, and zero configuration. Drop your files and go.
