Frequently Asked Questions

What people ask most about CSV Viewer

Why are my CSV columns wrong?

The file may use tabs, semicolons, pipes, quoted commas, or a different delimiter than expected. Check delimiter detection and header rows.

Is there a file size limit?

The practical limit depends on browser memory and device performance. Very large CSV files may be better opened in a database or spreadsheet tool.

Can I edit the data?

The CSV Viewer is read-only for safe data exploration. Use our CSV Sorter or CSV Deduplicator for data manipulation.

Is my CSV uploaded when viewing it?

CSV parsing runs in your browser. The selected file is not uploaded to Rune for viewing.

Does it auto-detect delimiters?

Yes, the parser automatically detects common delimiters including comma, tab, and semicolon.

Can I search across multiple columns?

Yes, the global search matches text across all columns simultaneously, making it easy to find specific records.

Why are leading zeros missing?

Some tools auto-detect numeric columns and remove leading zeros. Treat ZIP codes, SKU values, and IDs as text when exporting or converting.

Do I need spreadsheet software to view CSV files?

No. You can inspect delimited text in the browser, then use a spreadsheet or database if you need advanced editing.
