Inputs on the left, structured output on the right.
Beautify and format SQL queries instantly — client-side only, nothing is sent to a server.
Input — Unformatted
Output — Formatted
Use this free online SQL formatter to beautify and indent SQL queries for MySQL, PostgreSQL, SQL Server, SQLite, and other dialects. Paste a raw or compressed query and get back a clean, readable version with consistent keyword casing and structured indentation.
Whether you are reviewing a stored procedure, debugging a complex join, or preparing SQL for documentation, this formatter works entirely in your browser — no data is transmitted to any server.
Select your SQL dialect, choose an indentation style, and set keyword casing to uppercase, lowercase, or title case. The formatter supports SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, and most standard SQL constructs including CTEs and subqueries.
Compact mode collapses your query to a single line for embedding in code strings or configuration files, while pretty-print mode expands it for review.
Which SQL dialects are supported?
The formatter supports standard SQL which is compatible with MySQL, PostgreSQL, SQLite, SQL Server, and most major database engines. Dialect-specific syntax may render differently.
Does formatting change how my query executes?
No. Formatting only affects whitespace, indentation, and casing — it does not alter the logic or execution plan of your query.
Is my SQL sent to a server?
No. All formatting runs in your browser. Your queries are never transmitted or stored.

SQL Formatter — fast, consistent results via Toolversa. This page explains how to use SQL Formatter effectively, what to validate in the output, and how it fits alongside other Developer Utilities utilities on Toolversa. Whether you are running a one-off task or a recurring workflow, the guidance below helps you avoid common pitfalls and keep results consistent.
SQL Formatter is optimized for scenarios where you need developer diagnostics and data shaping results quickly, with minimal setup. It works well when your input is well-formed and your success criteria are clear (for example: correct formatting, expected file type, or a numeric result within a plausible range). If your needs are exploratory, start with a small sample input and expand once the output matches expectations.
Most issues trace back to input ambiguity: wrong encoding, missing required fields, mixed delimiters, oversized files, or mismatched units. Before running the tool again, re-check the field labels, required markers, and any format hints shown in the form. For file-based tools, confirm the file type matches what the tool expects and that the file is not corrupted.
Treat the first output as a draft. Compare against a known-good example, re-run with edge-case inputs, and verify any derived numbers with a second method when stakes are high. For text outputs, scan for truncation, unexpected characters, and line-break changes. For files, open the output in the target environment where it will be used.
Never paste production secrets, tokens, or customer data into public utilities without approval. Specifically for SQL Formatter, avoid submitting regulated personal data, secrets, or confidential client material unless your policy explicitly permits processing in this environment.
Many workflows are multi-step: prepare inputs with one utility, transform with SQL Formatter, then finalize with another. Keeping naming conventions consistent between steps reduces errors and makes automation easier later. If you frequently repeat the same sequence, document it as a short internal checklist.
If execution fails, check file size limits, network stability, and whether your account plan allows the tool. If output looks wrong but execution succeeds, simplify the input to isolate the issue: remove optional fields, reduce content size, or test a minimal example. When premium features apply, confirm your subscription includes access.
