+
+## Why even make this?
+
+Fair question. I view spreadsheets constantly at work—XLSX, XLS, CSV, ODS, you name it. The existing options were inadequate:
+
+**Microsoft Excel**: Bulky. Takes several seconds to open multi-megabyte files. Overkill for just viewing data.
+
+**Other VSCode extensions**: Tried them all. Common problems:
+- Can't open older XLS formats and refuse to read large files
+- Consume 500MB+ RAM for a few-megabyte file
+- Ship a full Excel-like editing experience nobody asked for
+
+**My requirements were simple**:
+1. Open any spreadsheet format instantly
+2. Display the actual data representation
+3. Reflect external edits immediately
+4. Not destroy my RAM
+
+Extensions shouldn't replicate Excel or some other tool. They should let you quickly iterate and validate data in context.
+That's what this does.
