JSON, SQL, XLSX, CSV, and TSV Converter: JSON, SQL, XLSX, CSV, and TSV Converter Online

A single flow for tabular data conversion

This converter covers common tabular data formats used across APIs, spreadsheets, exports, logs, and database fixtures. It accepts pasted text and uploaded files, including TXT files that are detected by content.

The tool normalizes input into a table preview first. That lets you inspect columns and rows before copying text output or downloading a spreadsheet file.

When each output format makes sense

JSON is useful for APIs and scripts. CSV and TSV are lightweight exchange formats for tables and logs. XLSX is practical for Excel and spreadsheet workflows. SQL INSERT is helpful for small seed datasets, fixtures, and quick database tests.

Object arrays become table columns, INSERT statements become rows, and XLSX input reads the first worksheet so the conversion remains predictable.

• JSON to CSV for opening API payloads in spreadsheet tools.
• CSV to JSON for scripts, test data, and import jobs.
• XLSX to TSV for clean copy-paste into internal tools.
• SQL INSERT to CSV for reviewing seed data as a table.
• CSV or TSV to SQL INSERT for quick database fixtures.

Privacy, detection, and practical limits

Main processing runs locally in the browser. Pasted content and selected files do not need to be uploaded to a backend for detection, preview, or text export.

Automatic detection handles valid JSON, SQL INSERT, CSV, and TSV. Very large XLSX files can still use significant memory, so splitting huge datasets is better on mobile devices.
