How it works

  1. Open Filelathe and drop your file (avoid macOS Finder Recents — use the real folder).
  2. A dedicated tool window opens for this format.
  3. Use the on-page controls to view or edit.

CSV opens as a compact table preview (sampled rows) so you can verify exports quickly.

Privacy

File bytes are read in your browser for viewing and playback. Unlike upload-to-convert sites, Filelathe is built around in-tab tools. API calls may use filename, type, and small samples to choose or invent a UI.
