SQL Query Generator
Transform raw tabular data into clean, syntactically correct SQL INSERT or UPDATE queries instantly.
Tip: Paste data directly from Excel or text files. Columns are auto-detected by tabs or spaces.
About SQL Query Generator
The SQL Query Generator turns raw multi-line text — typically rows copied from Excel — into syntactically correct SQL INSERT or UPDATE statements. It splits columns on tabs or spaces, keeps numbers as raw values and wraps strings in escaped single quotes.
It replaces the tedious manual work of typing quotes, commas and parentheses for hundreds of rows. UPDATE mode also lets one selected column become the `WHERE` key, making repeated row updates easier to prepare.
The generated text is a starting point for review, not a database connection: the tool does not execute SQL, inspect schemas or know column constraints. Input remains in the browser.
How SQL Query Generator works in practice
- 1Paste your raw data into the "Raw Input Data" area.
- 2Choose INSERT or UPDATE output.
- 3For UPDATE statements, select the column to use as the primary key in the WHERE clause.
- 4Copy the formatted SQL and paste it into your SQL client.
Jobs this tool is built for
- Convert rows copied from an Excel lookup sheet into INSERT statements for seed data.
- Prepare UPDATE statements for correcting a controlled list of records by primary key.
- Escape apostrophes in names and labels before building a one-off migration script.
- Create reviewable SQL from a small tabular export when bulk-import tooling is unavailable.
What you can do here
- Smart type detection — numbers stay raw, strings get quoted and escaped
- Handles tab-separated (Excel) and space-separated input
- INSERT and UPDATE statement modes
- Fully client-side — data never leaves your machine
Common questions about SQL Query Generator
How does it handle strings containing quotes?
Single quotes are escaped automatically (e.g. "O'Brian" becomes 'O''Brian') so the query won't break.
Can I copy directly from Excel?
Yes — Excel copies cells as tab-separated values, which the formatter splits into columns automatically.
Does the tool run the generated query?
No. It only creates SQL text. Review the table, columns, values and WHERE clauses, then execute it through your normal database client and transaction process.
How are NULL and date values handled?
Automatic detection is limited. Inspect generated values carefully and replace quoted placeholders with database-appropriate `NULL`, date casts or functions where needed.
