Everything you would otherwise open Excel for. Convert CSV to JSON, Excel, SQL, Markdown or Parquet, view and sort a million rows, repair broken quoting and encodings, dedupe, split, join two files on a key, pivot, profile the columns, and run actual SQL over a CSV without loading it anywhere.

What this kit does that a general converter doesn't. Real .xlsx read and write, and SQL over a CSV — no server, no row cap beyond your own memory.
