Is DataDevKIT free to use?

Yes. Every tool on DataDevKIT is completely free with no account required.

Does DataDevKIT upload my data to a server?

No. All processing happens in your browser using local memory and WebAssembly. Your data never leaves your device.

Can DataDevKIT open Parquet files?

Yes. The Parquet Inspector uses DuckDB WebAssembly to read .parquet files directly in your browser. You can then export the data as CSV or JSON.

How does CSV/JSON to SQL conversion work?

DataDevKIT automatically infers data types (INTEGER, NUMERIC, BOOLEAN, TIMESTAMP, VARCHAR) from CSV headers or JSON object fields and generates DDL CREATE TABLE scripts along with escaped INSERT INTO SQL statements.

Can I convert SQL back to CSV or JSON?

Yes. Paste raw SQL INSERT statements and DataDevKIT will parse values into formatted CSV spreadsheets or structured JSON arrays.

Is my dataset kept completely private?

Yes. All transformations run locally inside browser memory using client-side JavaScript and WebAssembly. No data is transmitted to servers.

How it works

Paste data, get SQL — in one step

Auto-detects types, escapes values, generates multi-dialect DDL.

Output-- Auto-generated from CSV input (PostgreSQL)

CREATE TABLE "users" (
  "id"      INTEGER,
  "name"    VARCHAR(255),
  "email"   VARCHAR(255),
  "salary"  NUMERIC,
  "active"  BOOLEAN,
  "joined"  TIMESTAMP
);

INSERT INTO "users" VALUES (1, 'Alice', 'alice@co.io', 75000, TRUE, '2024-01-15');
INSERT INTO "users" VALUES (2, 'Bob',   'bob@test.org', 62000, FALSE, '2023-06-20');
