How does CSV to SQL work?

Paste or upload CSV with a header row. Choose INSERT, UPDATE, or both. Set the table name (default your_table) and optional database name. The tool generates SQL using the first column as the UPDATE key.

Is my data uploaded to a server?

No. All conversion happens locally in your browser using JavaScript. Whether you paste text or use the file upload button, your CSV and JSON never leave your device and nothing is stored on a server.

Can I upload and download files?

Yes. Upload .csv for CSV-based modes or .json for JSON to CSV. After converting, download results as .sql, .json, .xml, or .csv depending on the active mode.

How do table and database names work for SQL?

Table name defaults to your_table. Database name is optional — leave it empty to omit the prefix, or enter a name to generate queries like `database`.`your_table`.

All tools

CSV to SQL

Generate SQL INSERT and UPDATE statements from CSV data. Set your table name (default: your_table), optionally add a database prefix, and choose INSERT, UPDATE, or both. Upload a .csv file and download a .sql file.

Private & local. Everything runs in your browser. Your CSV, JSON, XML, and SQL data are never uploaded to a server or stored anywhere — conversion stays on your device.

Conversion mode

CSV → SQL CSV → Array CSV → XML Array → CSV CSV → JSON JSON → CSV

SQL statement type

Example: INSERT INTO `your_table` (...)

CSV input

First row is used for column names. First column is the UPDATE key.

Conversion modes

Convert CSV to SQL INSERT and UPDATE
Generate SQL INSERT and UPDATE statements from CSV data. Set your table name (default: your_table), optionally add a database prefix, and choose INSERT, UPDATE, or both. Upload a .csv file and download a .sql file.
Convert CSV to JSON array
Turn CSV rows into a JSON array of arrays — each row becomes a nested array. Ideal for scripts, APIs, and data pipelines. Upload a .csv file and download .json output.
Convert CSV to XML
Transform CSV with a header row into XML. Each data row becomes a <row> element and each column becomes a child tag. Upload a .csv file and download .xml output.
Convert JSON array to CSV
Convert a JSON array of objects or nested arrays into CSV. Object keys become column headers automatically. Paste JSON or build from exported array data.
Convert CSV to JSON objects
Parse CSV with a header row into a JSON array of objects. Each column becomes a key and each row becomes an object. Upload .csv files and download formatted .json.
Convert JSON array to CSV
Transform a JSON array of objects into CSV with a header row from object keys. Upload a .json file and download .csv for spreadsheets or imports.

Array to CSV — nested JSON arrays or objects written as CSV
Upload .csv or .json files and download .sql, .json, .xml, or .csv output
Private by design — no data is sent to or stored on a server

Frequently asked questions

How does CSV to SQL work?: Paste or upload CSV with a header row. Choose INSERT, UPDATE, or both. Set the table name (default your_table) and optional database name. The tool generates SQL using the first column as the UPDATE key.
How does CSV to JSON work?: The first CSV row is treated as column headers. Each following row becomes a JSON object. Output is a formatted JSON array you can copy or download as a .json file.
What is CSV to Array?: Every CSV row is converted into a nested array inside a JSON array, without using headers as object keys. Useful when you need row-based arrays instead of keyed objects.
How does CSV to XML work?: The first CSV row is used as XML tag names. Each following row becomes a `<row>` element, and each column value is written inside its matching XML child tag. Output is formatted XML you can download as a .xml file.
How do JSON to CSV and Array to CSV differ?: JSON to CSV expects an array of objects and writes keys as the CSV header. Array to CSV also accepts nested arrays (each sub-array becomes a CSV row) or objects with the same header behavior.
Is my data uploaded to a server?: No. All conversion happens locally in your browser using JavaScript. Whether you paste text or use the file upload button, your CSV and JSON never leave your device and nothing is stored on a server.
Can I upload and download files?: Yes. Upload .csv for CSV-based modes or .json for JSON to CSV. After converting, download results as .sql, .json, .xml, or .csv depending on the active mode.
How do table and database names work for SQL?: Table name defaults to your_table. Database name is optional — leave it empty to omit the prefix, or enter a name to generate queries like `database`.`your_table`.
