CSV to SQL Converter

Uno strumento online gratuito per sviluppatori per generare istantaneamente istruzioni SQL INSERT o UPDATE da file CSV. Riduce il tempo e gli errori umani durante la migrazione dei dati in un database.

L'intero processo di conversione viene eseguito nel tuo browser. Anche se il file CSV contiene informazioni sensibili, non verrà mai inviato a un server esterno.

CSV (Valori Separati da Virgola)

Un semplice formato di testo che utilizza virgole per separare i valori.

SQL (Structured Query Language)

Linguaggio di programmazione standard per gestire dati in database relazionali.

Istruzione INSERT

Comando SQL utilizzato per aggiungere nuove righe (record) in una tabella del database.

Istruzione UPDATE

Comando SQL utilizzato per modificare i record esistenti, solitamente in combinazione con la clausola WHERE.

Escaping

Il processo che garantisce che i caratteri speciali in SQL (come virgolette singole) siano trattati come semplici stringhe.

Q.Is the CSV data I enter saved on external servers?

No, all input data is processed strictly within your PC or smartphone's browser. There is no transmission or storage of data to external servers, making it completely safe to use even with CSV files containing customer lists or sensitive information.

Q.Can it convert huge CSV files with tens of thousands of rows?

Yes, it can, but it depends on your browser's memory and processing power. Processing a few thousand to tens of thousands of rows usually completes in seconds. However, for extremely large files exceeding 100,000 rows, we recommend splitting the file before conversion to prevent browser freezing.

Q.How are numeric and string data distinguished?

The tool automatically analyzes the value of each cell internally. If it consists only of numbers (or numbers with a decimal point), it is treated as a number and quotes are removed. This automatic inference can also be disabled in the options, allowing you to force all values to be quoted as strings if required.

Q.How are NULL values or empty cells handled?

Empty cells or the string 'NULL' are output to SQL as `NULL` without quotes so that they are treated as official NULLs in the database. If you intentionally want them registered as empty strings (`''`), please adjust the CSV data beforehand or manually tweak the generated SQL.

Q.Can I use the output with both MySQL and PostgreSQL?

Yes, the basic INSERT and UPDATE statements are generated using standard SQL syntax, so you can use them directly in major relational databases like MySQL, PostgreSQL, SQLite, and SQL Server. If specific functions or dialects are required, please replace them in the output SQL using a text editor.
