CSV Viewer

What is CSV Viewer?

CSV (Comma‑Separated Values) is a simple file format used to store tabular data, such as spreadsheets or databases. Each line is a data record, and each record consists of fields separated by commas (or other delimiters). CSV files are widely used for data exchange between applications because they are plain text and easy to parse.

This tool helps you visualize CSV data in an interactive table. You can sort columns, toggle headers, and even copy the resulting HTML for embedding. It's perfect for quickly inspecting CSV files, debugging data exports, or sharing data with non‑technical users.

All processing happens locally in your browser. Your data is never uploaded to any server, ensuring privacy and speed.

How to Use

Step 1: Paste your CSV data into the input area. You can also type directly. The sample data shows the expected format.
Step 2: Check "First row as header" if your CSV has column names in the first row. If your file uses semicolon (;) as delimiter, check "Use semicolon".
Step 3: Click "View Table" to generate the interactive table.
Step 4: Click on any column header to sort the table by that column (ascending/descending).
Step 5: Use "Copy as HTML" to copy the table HTML for use in emails, reports, or websites.

The tool automatically handles quoted fields and escaped quotes. For large files, performance may vary, but typical datasets up to a few thousand rows work well.

Examples

Simple CSV:
Name,Age,City
John,30,New York
Jane,25,Los Angeles

Semicolon-separated:
Name;Age;City
John;30;New York
Jane;25;Los Angeles

Quoted fields:
"Name","Age","City"
"John","30","New York"
"Jane","25","Los Angeles"

Who Uses CSV Viewers?

• Business Users – viewing reports without opening Excel.

Pro Tips

• If your CSV uses a different delimiter (e.g., tab), you can replace it with comma or semicolon using a text editor before pasting.
• Click on column headers to sort data – useful for quickly finding highest/lowest values.
• For large files, paste the data and click "View Table". It may take a few seconds; the tool uses native JavaScript for speed.
• Use the "Copy as HTML" button to get a styled table that you can paste into email or web pages.
• Make sure your CSV follows standard formatting: no extra spaces, and fields with commas are quoted.
