How to Convert SQL Queries & Dumps into YAML Fixtures
Database developers, QA engineers, and automated testing frameworks frequently need seed data and test fixtures formatted as YAML. Relational databases export dumps as SQL INSERT statements or CLI terminal text grids, which can be awkward to read or incorporate into modern configuration pipelines and testing suites.
The SQL to YAML Converter operates 100% in your local web browser, parsing SQL INSERT queries, batch statements, or ASCII terminal grids (from MySQL, PostgreSQL, or SQLite). It strips SQL escaping, automatically converts numeric and boolean literals into native primitives, and formats the output into clean, human-readable YAML documents.
Dual Input Parsing
Parses both formal SQL INSERT queries (single & batch) and ASCII query dumps with border delimiters (+---+).
Multiple Output Structures
Export as an array of records (- id: 1), a table-keyed structure (users: [...]), or a dictionary keyed by row identifier.
100% Client-Side Privacy
Your proprietary queries and confidential database records remain strictly in your browser memory. Zero network transmission.
Step-by-Step Conversion Workflow
- Paste SQL Statements or ASCII Grid: Paste your INSERT query, dump script, or CLI terminal grid into the input editor or upload a
.sqlfile. - Select Output Mode & Formatting: Choose between array, keyed-table, or dictionary layout, and set your preferred indentation (2 or 4 spaces).
- Copy or Download YAML: Copy the formatted YAML text directly or download it as a ready-to-use
.yamlfixture file.
Frequently Asked Questions
Can I convert MySQL or PostgreSQL CLI terminal output into YAML?
Yes. The converter automatically recognizes ASCII query dumps with border characters (+---+---+ and | column |) from MySQL, PostgreSQL, or SQLite CLI tools and extracts them into YAML.
How are single quotes in string values handled?
Standard SQL doubled single quotes (e.g. 'O''Reilly Media') are automatically unescaped to clean characters ('O'Reilly Media') in the YAML output.
What is the difference between array, keyed-table, and dictionary outputs?
Array outputs a standard YAML list (- id: 1). Keyed-table wraps the list under the table name (users: [...]). Keyed-dictionary maps each record by a row identifier (row_1: {...}), ideal for dictionary lookups.
How are SQL NULL values represented in YAML?
You can choose between the standard 'null' literal or the idiomatic YAML tilde '~' character using the Null Format dropdown in the toolbar.
Are my SQL queries or database records sent to any remote server?
No. The entire conversion process executes 100% locally in your web browser. Zero SQL data is ever transmitted across the network.
