JSON转SQL

它属于「JSON 工具」分类：JSON 的格式化、结构变换与各种数据格式互转。

• 按 MySQL 语法生成 <code>INSERT INTO</code> 语句，标识符使用反引号包裹。
• 字符串中的单引号会<b>自动双写转义</b>，避免语法错误与注入风险。
• 勾选<b>批量插入</b>会合并成一条多值语句，导入大量数据时性能更好。
• <b>生成建表语句</b>会扫描全部数据推断字段类型（整数、小数、布尔、变长字符串）。
• 嵌套的对象与数组会被序列化成 JSON 字符串存入单个字段。

Generate INSERT statements and CREATE TABLE DDL from arrays.

Belongs to “JSON Tools”: Format, transform and convert JSON to and from various data formats.

• Generates <code>INSERT INTO</code> statements in MySQL syntax, with identifiers wrapped in backticks.
• Single quotes in strings are <b>automatically doubled/escaped</b> to avoid syntax errors and injection.
• Enabling <b>batch insert</b> merges rows into one multi-value statement — faster for large imports.
• <b>Generate CREATE TABLE</b> scans all data to infer column types (int, decimal, bool, varchar).
• Nested objects and arrays are serialized to a JSON string stored in a single column.

Free, no sign-up; everything runs locally in your browser and files are never uploaded.

3. Provide the input：Paste your content into the input box or drop a file onto the page; you can also click “Sample” to try example data first.
4. Adjust options and run：Adjust the options if needed, then click the process / convert / generate button.
5. Get the result：Everything runs locally in your browser; copy or download the result — your files are never uploaded.

FAQ

Which databases are supported?

Outputs MySQL/MariaDB syntax by default. For PostgreSQL or SQL Server, replace backticks with double quotes or brackets; the rest of the statement structure is the same.

Are the inferred column types accurate?

Types are inferred from the data and are for reference only. Confirm length limits, nullability, indexes and primary keys against your business needs.

Single vs. batch insert — which to choose?

Use single inserts for small data or step-by-step debugging; use batch for tens of thousands of rows to cut network round-trips and transaction overhead.

Is there an SQL injection risk?

The tool applies standard single-quote escaping. Still review the generated script before running it, especially with untrusted data.
