how to convert csv to excel
Drop your CSV file
Drag your CSV file into the drop zone above, or click the box to pick a file from your computer or phone. The browser reads the file directly — nothing uploads.
Click Convert
The page runs SheetJS on your device to decode the Comma-Separated Values and encode it as Microsoft Excel workbook. Most conversions finish in a few seconds; large or codec-heavy files (RAW, video) can take longer.
Download the EXCEL file
When the conversion finishes, the EXCEL file is ready to download. Save it anywhere on your device.
FAQ
common questions
Will my CSV's data types come through correctly in Excel?
Mostly. Numbers in the CSV are parsed as numbers in Excel (so SUM, AVERAGE, etc. work); dates in standard formats (YYYY-MM-DD, MM/DD/YYYY) are parsed as Excel dates and sort chronologically. Text stays as text. The CSV's lack of explicit type information means edge cases (leading zeros, very long numbers, dates in unusual formats) can be misinterpreted — Excel makes a best-guess based on appearance.
Can I add formulas after converting?
Yes — the XLSX is a fully editable Excel workbook once converted. Open in Excel, Google Sheets, or LibreOffice Calc and add formulas, pivot tables, charts, formatting as you would for any spreadsheet. The conversion gives you the data in a usable spreadsheet container; what you do with it is up to you.
What delimiter does the converter expect?
Comma by default — the C in CSV. The converter also handles common delimiter variants (semicolons, used in European locales where comma is the decimal separator; tabs, technically TSV). Quoted values with embedded commas parse correctly. Truly non-standard delimiters (pipes, custom characters) may need manual handling.
Will the column headers from my CSV become Excel column headers?
Yes — the first row of the CSV becomes the first row of the Excel sheet. To use those as proper sortable column headers, click into Excel and apply 'Format as Table' (Ctrl+T / Cmd+T) — that promotes the first row to header status and enables filtering, sorting, and structured references.
Why convert CSV to Excel?
Three common reasons: (a) you'll do analysis or reporting that needs formulas, pivot tables, charts — those are Excel features; (b) you're sharing with business stakeholders who expect XLSX; (c) you want richer data validation, formatting, or multiple sheets. For raw data exchange between systems, CSV is better; for human-friendly editing and analysis, XLSX is the right target.
