How to Use the CSV Viewer
The CSV Viewer tool lets you visualize any CSV (Comma-Separated Values) file as a clean, readable HTML table directly in your browser. To use it, paste your raw CSV text into the left panel. Select the correct delimiter from the dropdown — comma is the default, but you can also choose semicolon, tab, or pipe to match your file's format. Click View Table to render the data. The first row is automatically treated as the header and styled distinctly. Each subsequent row becomes a table row, and hovering highlights the row for easy reading. The tool also shows summary statistics: total row count, number of columns, and number of data rows. If your CSV uses quoted fields containing the delimiter character (for example a comma inside double quotes), those are handled correctly. Click Sample to load a four-column example with names, ages, cities, and emails. All processing happens locally in your browser — your CSV data is never uploaded to any server, which is important when working with confidential datasets.
Frequently Asked Questions
What is a CSV file?
›
CSV stands for Comma-Separated Values. It is a plain-text file format used to store tabular data where each line represents a row and each value within that row is separated by a delimiter, most commonly a comma. CSV files are widely used for exporting and importing data between spreadsheet applications, databases, and web services.
What delimiters does the CSV Viewer support?
›
The CSV Viewer supports four common delimiters: comma (,), semicolon (;), tab character, and pipe (|). European CSV exports from Excel often use semicolons instead of commas because the comma is used as a decimal separator in many European locales.
Can I upload a CSV file instead of pasting?
›
The current tool uses paste-based input for simplicity and privacy. To view a file, open it in a text editor (like Notepad or VS Code), select all, copy, and paste it into the tool. A file upload version is on our roadmap.
Why are my columns misaligned in the CSV Viewer?
›
Misaligned columns usually mean your CSV uses a different delimiter than the one selected. Try switching between comma, semicolon, tab, and pipe until the columns line up correctly. Also check whether quoted fields containing the delimiter are properly enclosed in double quotes.
