How to Convert CSV to Excel Without Breaking Bangla or Leading Zeros

Double-clicking a CSV file in Excel often goes wrong. Bangla text becomes strange symbols, a phone number such as 01712345678 loses its first zero, and long IDs turn into scientific notation. The CSV to Excel tool avoids those problems.

Quick answer

Add your CSV or paste a text list, choose the separator if needed, and download an XLSX. Text is read as UTF-8, numbers beginning with 0 stay as text, and real numbers remain numbers.

Why Excel breaks CSV files

• Encoding. Excel assumes a legacy encoding unless a special marker is present, so UTF-8 Bangla looks garbled.
• Automatic typing. Excel guesses that 0171... is a number and removes the zero.
• Dates. Values like 3-4 can be changed into dates.
• Long numbers. 16-digit values are shown as 1.23E+15.

What the tool does differently

1. Reads the file as UTF-8.
2. Detects comma, semicolon or tab separators.
3. Keeps values with a leading 0 as text.
4. Stores genuine numbers as numbers so formulas work.

Steps

1. Open the tool and add a CSV or paste data.
2. Pick the delimiter if auto-detect is wrong.
3. Download the XLSX file and open it in Excel, Google Sheets or LibreOffice.

Tips

• Keep the first row as headers.
• If a column of IDs must stay as text, check the result in Excel's format cell dialog.
• For the reverse direction, use Excel to CSV, which produces one CSV per sheet.
