Help

When should I use CSV to Excel conversion?

Use it when you want to open CSV data such as store orders, ad reports, statistics, or member lists in Excel in a more readable workbook format.

What is a delimiter?

CSV files separate columns with symbols such as commas, semicolons, tabs, or pipes. If all values appear in one column, the selected delimiter may not match the actual file delimiter.

Are Excel styles restored during conversion?

CSV is a text-based data file, so it does not include colors, merged cells, fonts, or formula display styles. This tool converts CSV rows and columns into an XLSX file.

Is the file uploaded to the server?

This utility reads CSV files and creates Excel files in the browser. In normal use, CSV files are not stored on the server.
