How to Use SQL Query Runner

Paste CSV data or load a CSV file to create an in-browser table named data. Then run practical SQL-style queries such as SELECT *, SELECT specific columns, COUNT(*), WHERE filters, and LIMIT clauses. This MVP is intentionally scoped for fast client-side analysis without introducing a heavy database dependency.

1

Load a dataset

Paste CSV data or upload a CSV file so the first row becomes the table header and the rest become rows.

2

Write a query

Query the table as data using SELECT ... FROM data with optional WHERE and LIMIT clauses.

3

Inspect the result set

Run the query to see the returned rows and verify your filtering or projections instantly.

What syntax is supported?+
This version supports SELECT, column projection, COUNT(*), simple WHERE comparisons, LIKE, and LIMIT against a single CSV-backed table named data.
