Extract text from CELL files
To convert your CELL file to another format, you need Hancom_Office or other Spreadsheet software.
To convert other file formats to the "Office Workbook" file type, you need software like Hancom_Office or a similar tool.
A .CELL file is a spreadsheet workbook created by Hancom Office Cell (formerly known as ThinkFree Office), a popular office suite developed by Hancom. Similar to the modern Microsoft Excel XLSX format, .CELL files use a ZIP-compressed container to store XML-based data, formulas, charts, and formatting. While this architecture is technically robust, the format is proprietary and rarely supported outside of the Hancom ecosystem.
The primary problem for users is that standard spreadsheet software - including Microsoft Excel, LibreOffice, and Google Sheets - cannot natively open .CELL files. Attempting to force-open them often results in garbled text or XML parsing errors. This creates significant workflow barriers when sharing financial data or reports internationally. To make the file usable, the most pragmatic solution is converting it to a universally accepted standard. Convert to XLSX if you need to retain formulas and edit the data, CSV for importing raw data into databases, or PDF for archiving read-only financial statements.
Convert.Guru analyzes your CELL file, detects the exact format, and lets you read the text inside.
Users also converted XLSX files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CELL converter.
