What is a .230 file?
The .230 file extension is an older format associated with early versions of Microsoft Excel, specifically Excel 1.0. It was used to store spreadsheet data, including numbers, text, and basic formatting. As spreadsheet software evolved, this format was superseded by more advanced and robust file types like .XLS and later .XLSX. While not commonly used today, some legacy data archives might still contain files in this format. Modern spreadsheet applications may struggle to open these files directly without specialized conversion tools or plugins due to significant differences in file structure and feature support compared to current standards. It represents a foundational step in the history of digital spreadsheets.

Frequently Asked Questions
No, the .230 format is considered obsolete and is not used for current spreadsheet creation or sharing. It is primarily encountered in historical data archives.

The most reliable method is to use Microsoft Excel (if it can open it) and then save it in a modern format like .XLSX. Alternatively, online file converters exist that might support this legacy format, but use them with caution for sensitive data.
Technical Details
The .230 file format is a binary file format used by Microsoft Excel 1.0. It contains spreadsheet data in a proprietary structure that differs significantly from modern .XLSX files, which are based on XML. Opening these files often requires specific legacy software or conversion utilities that can interpret its unique encoding and data organization.
