Data Exploration tips

🔍

Drop a CSV into the dropzone or paste data directly. Auto-detection figures out comma vs tab vs semicolon delimiters.

💡

Click any column header to sort. The numeric vs string sort is auto-detected per column — numbers sort numerically, dates and strings alphabetically.

🎯

Use the search box to filter rows. Searches every column simultaneously — useful for finding a specific record in large dumps.

🔒

CSVs are parsed entirely client-side. Sensitive data (customer lists, financials) never leaves your browser.

Dewiswch Ffeil

Drop your file into the tool above. It stays entirely on your device — nothing is sent to any server.

Proses

The tool processes your data instantly in your browser using JavaScript. No server, no waiting.
