Free No signup Client-side Privacy friendly

How to use

  1. 1 Paste your CSV data.
  2. 2 Enter the target table name and choose the SQL dialect.
  3. 3 Toggle "Include CREATE TABLE" to add a best-guess schema at the top.
  4. 4 Copy or download the generated SQL — one INSERT per row.

Why use this tool

  • Four dialects — MySQL, PostgreSQL, SQLite, SQL Server. Identifiers quoted appropriately for each.
  • String literals use single-quote doubling — portable across all four targets.
  • Cell type inference — empty becomes NULL, numbers stay unquoted, everything else escaped string.
  • Optional CREATE TABLE with best-guess column types (INT / DECIMAL / TEXT).

Frequently asked questions

How are NULLs detected?

Any empty cell becomes the literal NULL (no quotes). To insert an empty string instead, set the cell to a single space or modify the SQL output.

Does it handle Postgres-specific types like JSONB?

No — column inference is limited to INT, DECIMAL, TEXT. Edit the CREATE TABLE manually if you need JSONB, ARRAY, or other extended types.

Will the SQL be properly formatted?

One statement per line. For pretty-printing, run the output through the <a class="text-brand-600 hover:underline" href="/sql-formatter">SQL Formatter</a>.
