2026/11/12 V1.0 Released. First Release. Open very large CSV, TSV, Excel, JSON and XML files in a grid, with memory that does not grow with the file size. Scroll, use "Go to row", or Ctrl+Home / Ctrl+End on a file with millions of rows. Pick a worksheet in Excel, and a record path in JSON/XML; expand nested values into columns. Find a value in the whole file, copy a selection, and export the current view as CSV or TSV. Auto-fit columns, read a clipped cell in full on hover, and remember the window and column widths. Open several files in tabs and reopen recent files; unsupported or binary files are named as such.
