Could you build this?
Partial The viewer and export UI are standard desktop app work, but fast, memory-safe exploration of multi-gigabyte files across many formats (Parquet, SQLite, Excel, JSONL) requires careful streaming and indexing.
What it would actually take: Use Tauri or Electron with a native or Rust/Go backend that parses files as streams, builds lazy indexes, and pages results into the UI. Format support for Parquet and SQLite is best done through existing libraries. Making multi-GB files responsive takes systems-level engineering in memory and I/O management.
