CSV to Excel Converter — Free & Online
CSV to Excel is a free, in-browser converter that turns CSV data into a real .xlsx spreadsheet without uploading your file. Paste CSV or drop a .csv file, preview the table, and download an Excel workbook that opens straight in Excel, Google Sheets, or LibreOffice. Numeric cells become real numbers (so totals and sorts just work), quoted fields with commas and line breaks are handled per RFC 4180, and columns are auto-sized — all processed locally on your device.

Frequently Asked Questions
How do I convert CSV to Excel?
Paste your CSV (or upload a .csv file) into TryDocsy's CSV to Excel converter, check the preview, then click Download Excel. You get a real .xlsx file that opens directly in Microsoft Excel, Google Sheets, or LibreOffice.
Will numbers be treated as numbers in Excel?
Yes. With “Numbers as numbers” on, clean numeric and true/false cells become real Excel numbers and booleans (so you can sum and sort them), while things like phone numbers and zero-padded codes such as 007 stay as text.
Does it handle quoted fields with commas and line breaks?
Yes. The CSV parser follows RFC 4180, so quoted values containing commas, newlines, or escaped quotes are placed into a single cell correctly rather than spilling across columns.
Can I choose the delimiter?
Yes. The delimiter is auto-detected, or you can force comma, semicolon, tab, or pipe — handy for European CSVs (semicolons) and TSV files.
Is my data uploaded to a server?
No. The .xlsx is generated entirely in your browser with a JavaScript spreadsheet engine. Your CSV never leaves your device, so it's safe for confidential data.
Does it name the sheet and size the columns?
Yes. You can set the sheet name, and columns are auto-sized to fit their content so the spreadsheet is readable the moment you open it.
