Why upload a JSON schema?
AI-SQL-Chat maps the table and column names from your schema.json file to generate
a single valid SELECT query exactly for that database structure. This makes the answers more
accurate and reduces the risk of errors. You can prepare the schema in a few minutes based on the
short guide (MySQL/PostgreSQL/SQL Server/Oracle).
How does this page work?
- Upload a
.jsonfile with your tables/columns structure (below). - Type your request in natural language — the tool suggests a single SELECT query.
- Copy the SQL and use it in your BI / tools, or go to the demo version.
Security
- Anti-SQLi filtering (blocks DDL/DML, OUTFILE/INFILE, SLEEP/BENCHMARK),
- enforced
LIMITand a single statement only, - no persistent storage of results (browser only),
- details in the Security section.
Short how-to
The app generates SQL queries based on the schema.json file you upload (map of tables and columns). You write a request in plain language and the system returns a single SELECT query that matches your schema.

FAQ — JSON schema
How do I prepare the schema.json file?
Use short SQL queries for your database engine (MySQL/PostgreSQL/SQL Server/Oracle) and export the result to JSON. See the guide: schema → JSON.
Is the query result stored anywhere?
No. Results are not stored persistently — we process them only in browser memory for the duration of handling the request.
Does the tool modify data in the database?
No. The system generates and allows only a single SELECT query (read-only), with enforced LIMIT and anti-SQLi filters.
