About the CSV to Excel Converter
Turn a CSV file into a proper Excel (XLSX) workbook so it opens cleanly in Excel with real columns instead of one jumbled line. The conversion runs in your browser and keeps your data private.
How to use it
- Drop your .csv file onto the box, or click to browse.
- Click Convert to Excel.
- Rows and columns are placed into a real spreadsheet.
- Download the .xlsx file.
Open exports from apps and databases as a tidy Excel file you can format, filter and chart. It all happens locally in your browser, so your data is never uploaded.
Frequently asked questions
Will my columns split correctly?
Yes — the converter parses the CSV into separate columns, handling quoted values and embedded commas.
Does it keep leading zeros?
Values are imported as-is. Codes with leading zeros may be shown as numbers in Excel; format the column as text if needed.
Is my CSV uploaded?
No. CSV to Excel runs entirely in your browser, so nothing leaves your device.
Can it handle large CSV files?
Yes, within your device's memory. Very large files may take a few seconds to process.
