Usage Guide
Markdown tables in docs hold config references, test data or seed data — but importing them into databases requires writing INSERT statements by hand. This tool converts Markdown tables directly into SQL INSERT or CREATE TABLE + INSERT statements with automatic type inference, local generation.
1. How to use
- Paste Markdown table text (with headers and data rows).
- Choose mode: INSERT only (into existing table) or CREATE TABLE + INSERT (includes DDL).
- Specify table name; the tool infers column types (VARCHAR/INT/BOOLEAN) from data and generates executable SQL.
2. SQL output caveats
- VARCHAR lengths are estimated from max data length — manually adjust for production-grade sizing.
- Boolean inference relies on true/false strings; yes/no or 1/0 may become VARCHAR and need manual correction.
- Single quotes and special characters are escaped, but application-layer SQL injection protection is still required.
- MySQL / PostgreSQL / SQLite type syntax differs — verify DEFAULT and NULL constraints match the target database.
3. The complete data import flow
SQL generation is one step in the import pipeline: Markdown table → SQL statements → local database test → production execution. This tool produces basic INSERTs without transaction wrapping or ON CONFLICT handling; if the target table has unique constraints, add ON CONFLICT DO UPDATE (PostgreSQL) or INSERT IGNORE (MySQL) manually. For bulk data, converting to CSV and using native COPY commands is an order of magnitude faster than individual INSERTs.
FAQ
Completely free with no registration. Table parsing and SQL generation run entirely in your browser.
Yes. A CREATE TABLE statement is auto-generated from the header row along with INSERT statements, with a customizable table name.
Column types such as VARCHAR or INT are inferred from the data content of each column and can be adjusted manually.
