| File extension | .CSV |
| Category | Document File |
| Description | CSV is a plain text format used for representing database tables. Each data box (cell) is enclosed in commas. Each line is a table row with data cells. It is a perfect format for transporting tables from one application to another. CSV files can be edited in OpenOffice Calc, MS Excel and many others. Being a plain text in actual fact, CSV tables are compatible with various text editing programs. It doesn't support formatting, so any data structuring is made with the use of special characters. |
| Associated programs | The CSV file format is very simple and supported by almost all spreadsheets and database management systems |

Quick answer: To convert CSV to XLS, upload your .csv file to our free online converter, which auto-detects the delimiter and encoding and parses each line into spreadsheet cells, then click Convert and download a ready-to-use Excel XLS workbook with formulas, formatting, and charts now possible. It runs in your browser with nothing to install.
CSV is plain text — no formulas, no formatting, no multiple sheets. The moment you need to calculate, format, or chart the data, you need Excel. This online converter parses your CSV into columns, detects the delimiter and encoding, and outputs a real XLS workbook ready for analysis. No software, free, up to 50 MB. Upload your .csv file and download the XLS in seconds.
CSV is the universal data exchange format — every database exports it, every API delivers it, every analytics tool ingests it. But CSV is plain text: no formatting, no formulas, no multiple sheets, no charts. The moment you need to actually work with the data in a spreadsheet — apply formulas, format columns, build PivotTables, create charts — you need Excel. Converting CSV to XLS produces a proper Excel workbook with the data parsed into columns, headers in row 1, and the structure ready for analysis. Drop your .csv file above and download an Excel spreadsheet in seconds.
The converter auto-detects the delimiter (comma, semicolon, tab, or pipe), reads the character encoding (UTF-8 with or without BOM, UTF-16, Windows-1252, ISO-8859-1, KOI8-R), and parses each line as a row in the output spreadsheet. Quoted fields containing embedded commas, line breaks, or quote characters per RFC 4180 are handled correctly — values stay in the right cells regardless of content complexity.
Cell types follow the source text: whole numbers become Excel number cells, while decimal values, percentages, currency amounts, dates and times stay as text exactly as they appear in the CSV, and values with leading zeros such as 00123 keep their zeros. The output is a standard .xls workbook ready for Excel, Google Sheets, LibreOffice Calc, Power BI, and any tool that accepts spreadsheet input.
