What this workflow does, step by step

Each step is a real operation we’d run in a single tool. Use the workflow when you want the whole pipeline in one click; jump to an individual tool when you only need one piece.

1. 1
   Inspect XLSX →

   Read sheet names + column headers via SheetJS, browser-side.

2. 2
   Filter rows

   In-memory filter by column = value (contains / equals / >, < / not blank). No standalone tool — this is the workflow-specific step.

3. 3
   Re-export to CSV or JSON →

   Convert the filtered rows into CSV (via papaparse) or JSON.
