CSV to Excel — Clean Spreadsheets from Raw CSV Files

CSV files are great for storing and exchanging data, but they're bare-bones when it comes to formatting, styling, and features we expect from Excel. Plainscan automatically detects delimiters, preserves character encoding, applies proper data types, formats headers, and generates a clean XLSX workbook ready for Excel, Google Sheets, Apple Numbers, and more.

Why Convert CSV to Excel?

When you double-click a CSV file, Excel may interpret delimiters incorrectly, convert long numbers into scientific notation, remove leading zeros from ZIP codes, misread dates, or display non-English characters incorrectly. Plainscan uses controlled parsing rules to preserve your original information while creating a properly structured Excel workbook you can trust.

How It Works

  • 1
    Upload Your CSV File: Send your CSV file — standard comma-separated, semicolon-delimited, TSV, or custom-delimited. We handle UTF-8, UTF-8 BOM, Latin-1, and more.
  • 2
    Preview and Configure: Review detection results, specify whether the first row contains headers, choose data types, and verify formatting preferences.
  • 3
    Download Your Excel File: Receive a fully formatted XLSX workbook with structured columns, styled headers, preserved data integrity, and improved readability.
