Files — Free Online Browser Tools

File tools handle real-world file work without a single upload: view CSVs as sortable tables, convert between CSV and JSON, verify checksums, clean and detect duplicate filenames, preview ZIP contents, and inspect file metadata. Your files stay on your device and are processed entirely in the browser. Inspect a CSV as a sortable, searchable table before importing it, or convert it to JSON for an API. Verify that a downloaded file checksum matches the published one, preview ZIP contents before extracting, and clean or detect duplicate filenames when organizing a messy folder. There are no size caps or upload queues — even large files process locally at full speed.
