CSV to Excel
Open a CSV as a proper Excel workbook: numbers as numbers, leading zeros kept, a bold frozen header and a filter on every column.
Paste cells or a Google Sheets link
Output
How it works
Add your CSV
Drop in a file, paste cells copied from Excel or Google Sheets, or paste a Google Sheets link.
Check the table
Every column is shown with what it holds - numbers, dates or text - so you can see it was read right before you save it.
Download the Excel file
Or copy it, or send it straight to a new Google Sheet. Nothing is uploaded at any point.
CSV to Excel converter: free and online
Convert CSV to excel in your browser: drop in a CSV file and download the Excel. The file is converted on your own device and never uploaded, so this csv to excel converter is safe for private and confidential files.
CSV is plain-text rows and columns, read by Excel, Google Sheets and every database. Excel workbooks (XLSX) are the spreadsheet format of Microsoft Excel.
Every row and field comes across, and nothing is sent to a server, so it is safe for client lists and private locations.

Why it matters
Private by design
Bank statements, payroll and customer lists never leave your computer: the file is read and written in your browser.
Nothing silently changed
Leading zeros, long ID numbers, commas inside quotes and line breaks inside cells come through exactly as they were.
Numbers stay numbers
Values like 1,234.50, $1,200 and 7% are recognised, so Excel and JSON get real numbers rather than text.
Questions
How do I convert CSV to Excel?
Drop your CSV file on this page, check the preview, and press Download. The Excel is made in a few seconds, with no sign-up.
Is my CSV file uploaded anywhere?
No. The csv to excel conversion runs in your browser, on your own device. The file never leaves it.
Are commas, quotes and line breaks inside cells handled?
Yes. Cells are read and written to the CSV standard (RFC 4180): a cell with a comma, a quote or a line break is quoted, and quotes inside are doubled, so nothing splits into the wrong column.
Will leading zeros and long numbers survive?
Yes. Cells are kept as the text they were: 00123 stays 00123 and a 16-digit account number is not turned into 1.23E+15. In Excel output, such cells are stored as text for exactly that reason.
Does it work with Google Sheets?
Paste a Google Sheets link (shared as "Anyone with the link") or copy the cells and paste them. To send a result to Google Sheets, use Open in Google Sheets: the table is copied and a new sheet opens, ready for Ctrl+V.
Is my data uploaded?
No. The whole conversion runs in your browser, so the file never leaves your computer.
Can it open a password-protected PDF or Excel file?
Yes. Drop it in and you are asked for the password; the file is unlocked in your browser and the password is never sent or saved. PDFs locked with RC4 or AES (up to AES-256, PDF 2.0) and Excel workbooks saved with Encrypt with Password both open. A PDF that only restricts copying or printing opens without asking. Without the password nothing is guessed: the file stays shut.
How big a file can it handle?
Hundreds of thousands of rows are fine on a normal laptop; the preview shows the first rows and the download has them all.
