JSON → SQL developer guide
Converts JSON to SQL INSERT statements in your browser, with the same local processing as the other FastMinify tools.

Developer notes

Validate inputs upstream. Reverse conversions may be lossy depending on format. Large files: prefer desktop browsers.

Conversion options

Table name
Name of the SQL table used in the INSERT statements. Characters other than letters, digits and underscores are replaced by an underscore, and the default is data.

Use cases

Quick prototyping between formats. Lightweight CI pipelines without middleware. Config review before commit.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter is auto-detected from the first line (comma, semicolon, tab, or pipe) — toggle whether row 1 holds column names. JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.

Examples

Basic example

Input

[ { "id": 1, "email": "[email protected]", "tier": "gold", "active": true }, { "id": 2, "email": "[email protected]", "tier": "silver", "active": false } ]

Output

INSERT INTO data (id, email, tier, active) VALUES (1, '[email protected]', 'gold', 1); INSERT INTO data (id, email, tier, active) VALUES (2, '[email protected]', 'silver', 0);

Second example

Input

[ { "id": 1, "email": "[email protected]", "tier": "gold", "active": true }, { "id": 2, "email": "[email protected]", "tier": "silver", "active": false } ]

Output

INSERT INTO data (id, email, tier, active) VALUES (1, '[email protected]', 'gold', 1); INSERT INTO data (id, email, tier, active) VALUES (2, '[email protected]', 'silver', 0);
