Frequently Asked Questions

How do I open a CSV file without Excel or Google Sheets?

Upload your CSV file to this tool or paste the raw text directly into the text area. The file is parsed entirely in your browser and displayed as an interactive table. No software installation, no account sign-up, and no data leaves your device.

Can I edit cells directly in the table?

Yes. Click any cell to switch it to edit mode. Type your new value, then press Enter or click outside the cell to save. All edits stay in memory until you download the updated CSV, so you can make as many changes as you like before exporting.

How do I sort and filter the data?

Click any column header to sort the table by that column. Click again to reverse the sort order. Use the search box in the toolbar to filter rows — it matches across all columns simultaneously, showing only rows that contain your search term.

Can this tool handle large CSV files?

The tool paginates data at 100 rows per page to keep the browser responsive. Files with tens of thousands of rows work well. Very large files (over 50 MB) may be slower depending on your device's memory and processing power.

How do I export or download the edited CSV?

Click the Download CSV button in the toolbar. The exported file reflects all your edits, added rows, and deleted rows. The download uses comma as the delimiter and properly quotes fields that contain commas or newlines.

What delimiters are supported?

The tool supports comma, semicolon, tab, and pipe delimiters. By default it auto-detects the delimiter by analyzing the first few lines of your file. You can also select a specific delimiter from the dropdown before loading the data.

Is my data private and secure?

All processing happens entirely in your browser. Your CSV file is never uploaded to any server. This makes the tool safe for confidential data, financial records, customer lists, and any other sensitive information.

Can I add or delete rows?

Yes. Use the Add Row button to append a blank row at the bottom of the table. To delete rows, check the selection boxes on the rows you want to remove, then click Delete Selected. Both operations are reflected in the downloaded CSV.
