Frequently Asked Questions

What is a CSV file?

CSV (Comma-Separated Values) is a simple file format used to store tabular data. Each line represents a row, and values are separated by commas. CSV files are widely used for data exchange between different applications, databases, and spreadsheets.

How do I upload and edit a CSV file?

To upload a CSV file, simply drag and drop it onto the upload area or click to browse and select the file. Once uploaded, you can click on any cell to edit its content, add new rows with the Add Row button, or delete rows using the trash icon.

Can I filter and search data in CSV files?

Yes! You can search across all data using the search box, or filter by specific columns using the column filter dropdown. Additionally, you can sort data by clicking on any column header. All filtering and sorting operations are performed in real-time.

Can I export the edited CSV data?

Absolutely! You can export your data in two formats: CSV (to maintain compatibility with spreadsheet applications) or JSON (for use in web applications and APIs). Click the Export CSV or Export JSON button to download your data.

Is there a file size limit for CSV uploads?

The tool supports CSV files up to 5MB in size. For most use cases, this is sufficient for thousands of rows of data. All processing is done client-side in your browser for maximum privacy and security.

Can I edit column headers?

Yes! Click on any column header to edit it. The tool will automatically update all data references to use the new header name. This is useful for renaming columns or fixing header formatting issues.

How does the CSV editor handle data privacy?

All CSV file processing, editing, filtering, and exporting is performed entirely in your browser using JavaScript. No data is uploaded to our servers or transmitted anywhere. Your files remain completely private and secure on your device.

What statistics does the tool provide?

The CSV viewer displays real-time statistics including total rows, number of columns, filtered rows count, and total data points. These statistics update automatically as you edit, filter, or modify your data.
