Excel/CSV to JSON

Import CSV text or XLSX: first row becomes JSON keys. Great for seeding APIs and databases from spreadsheets.

{{ excelToJson.xlsxFileName }}

{{ t("excelToJsonXlsxHint") }}

{{ excelToJson.message }}

Overview

Developers often get spreadsheet exports and need JSON for fixtures, migrations, or imports. This tool treats the first row as headers and each following row as an object.

CSV mode follows the same comma and quoting rules as CSV to JSON. XLSX mode reads the first worksheet; empty cells become empty strings.

Very large files can stress tab memory; split sensitive data before processing.

FAQ

What is this tool for?

It runs fully in your browser: useful to validate, format, or convert data in everyday development.

Are my inputs sent to a server?

Processing happens locally with JavaScript. We do not store what you paste into the text areas.

Can I use this for real production data?

Use at your own risk. For secrets (passwords, tokens), prefer controlled environments and your company policies. And always review the generated contents. Never trust blindly things you see on the internet.
