Comma-Separated Values (CSV) files are among the most commonly used formats for storing and exchanging data. But what happens when you don’t have Excel or any spreadsheet software installed?

🧾 What is a CSV File?
A CSV file stores tabular data in plain text, where each line corresponds to a row and each value is separated by commas. It’s widely used in business, finance, research, and web applications for exchanging structured data due to its simplicity and compatibility.
Whether it's exported from Excel, Google Sheets, or a database, CSV remains a universal choice for data transport.

🧠 CSV Files: A Brief History
CSV files date back to the early days of computing when mainframe systems needed a simple way to export rows of data. Over time, they’ve remained unchanged and are still one of the most compatible formats across platforms — supported by almost every spreadsheet and database application.
How to Use the CSV Viewer
- Open the Excel viewer — CSV is handled there, alongside XLS, XLSX, ODS, XLSM, XLSB, XLTX and XLTM.
- Upload your
.csvfile, up to 20 MB. - Read the rows in a scrollable table.
Exported data displays as columns instead of raw text. The same page opens XLS and XLSX workbooks, and those two — not CSV — convert to PDF, JPG or PNG, up to 5 MB.
