Ask AI to build a small offline dashboard from a CSV

Fictional rows; local file processing, no connection or tracking. This example runs locally; files selected here stay in browser memory.

Inspect an actual local dashboard

A filter changes scope. Keep known subtotal and unavailable count visible; do not replace a blank with zero.

Take the technique to your next job

Build a small offline HTML/JavaScript dashboard for this supplied CSV and data dictionary. Answer [specific question] with [needed filters]. Preserve record IDs, valid zero and missing values; apply the supplied duplicate policy. Show included rows, known subtotal and missing count. Keep processing local: no external libraries, network calls, tracking, credentials or service integrations. Provide the actual files and a plain explanation. Include independent known-answer and awkward cases for filters, blanks, quotes and invalid input; do not claim production readiness.
