Question 1

What is a CSV file?

Accepted Answer

CSV stands for Comma-Separated Values. It's a simple text file format where each line represents a row of data, and values within each row are separated by commas. CSV files are widely used for storing tabular data and can be opened by spreadsheet applications like Excel and Google Sheets.

Question 2

Is this CSV opener free to use?

Accepted Answer

Yes, our CSV opener is completely free to use. There's no signup required, no file size limits for reasonable files, and no watermarks. Simply upload your CSV file and view your data instantly.

Question 3

Is my CSV data secure?

Accepted Answer

Your data never leaves your browser. All CSV parsing and viewing happens locally on your device. We don't upload, store, or have access to any of your data. Once you close or refresh the page, the data is gone.

Question 4

What CSV formats are supported?

Accepted Answer

We support standard CSV files with comma separators. The tool automatically detects headers in the first row. Most CSV files exported from Excel, Google Sheets, databases, and other applications will work correctly.

Question 5

Can I edit my CSV data?

Yes! You can directly edit cells in the spreadsheet view. Click on any cell to modify its value. You can also copy the data to your clipboard and paste it into any spreadsheet application.

Question 6

How do I create a chart from my CSV data?

After uploading your CSV file, click the 'Create Chart' button. This will take you to our chart editor where you can paste your data and choose from various animated chart templates including bar charts, line charts, and pie charts.

Question 7

What's the maximum file size I can open?

Accepted Answer

Since all processing happens in your browser, the limit depends on your device's memory. Most devices can handle files up to 50MB without issues. For very large files, we recommend using a desktop spreadsheet application.
