What is a CSV Viewer & Converter?
CSV (Comma-Separated Values) files are the universal format for exporting tabular data from databases and spreadsheets, but raw CSV text is hard to read at a glance. This tool instantly parses it into a clean, scrollable HTML table right in your browser — no spreadsheet software needed.
Beyond viewing, it can convert your data into two developer-friendly formats: a formatted JSON array and a Markdown table. Everything runs locally, so even large files process quickly and your data never leaves your machine.
Common Uses
- Data Analysis: Upload a CSV export from an analytics platform and scan it visually without opening Excel or Google Sheets.
- API Development: Convert tabular data to a JSON array to quickly mock up API responses or seed a database.
- Documentation: Paste a CSV and copy the Markdown table output directly into a README or wiki page.
Frequently Asked Questions
Is my CSV data uploaded to your server?
No. Everything runs entirely client-side inside your browser using JavaScript. When you paste text or upload a file, it is processed locally on your machine — no data is ever sent to a server.
Is this csv viewer free?
Yes, completely free — unlimited use, no login, no paywalls.
How do I convert CSV to JSON?
Simply paste your CSV data into the input box or upload a .csv file. The tool automatically detects the first row as headers and converts the rest of the rows into an array of JSON objects. Click the "JSON" tab to view and copy the beautifully formatted JSON output.
Does this tool handle commas inside quotes?
Yes. Our CSV parser strictly follows the RFC-4180 standard. It correctly parses complex CSV files, including cells that contain internal commas, escaped quotation marks, and line breaks wrapped inside quotes.
