What it does

  • Browse groups, channels and the properties attached at every level
  • Export CSV, or CSV that keeps the properties a plain export discards
  • Streams segment by segment, so files larger than memory still open
  • Reads a file killed mid-write, keeping everything before the broken tail
  • Runs fully offline; five UI languages
