Convert 123 to XLSM

Understanding 123 and xlsm file formats

123 files are spreadsheet documents created by Lotus 1-2-3, a pioneering spreadsheet application popular in the 1980s and 1990s. These files typically have the .123 extension and contain data, formulas, and formatting specific to Lotus 1-2-3.

XLSM files are macro-enabled spreadsheets used by Microsoft Excel. The .xlsm format supports advanced features such as VBA macros, complex formulas, and modern Excel functionalities.

Why convert 123 to xlsm?

Converting 123 files to xlsm allows users to access legacy Lotus 1-2-3 data in modern Excel, enabling macro support and advanced spreadsheet features.

How to convert 123 to xlsm

Direct conversion from 123 to xlsm is not natively supported in most modern software. The process typically involves two steps:

1. Convert 123 to XLS/XLSX: Use a compatible program to open the 123 file and save it as an Excel file.
2. Save as XLSM: Open the converted file in Excel and save it as an XLSM file to enable macro support.

Recommended software for conversion

• LibreOffice Calc: LibreOffice Calc can open many Lotus 1-2-3 files. Open your .123 file in Calc, then use File → Save As and choose Microsoft Excel 97-2003 (.xls) as the format.
• Microsoft Excel: Open the converted .xls file in Excel. To save as .xlsm, use File → Save As and select Excel Macro-Enabled Workbook (*.xlsm).
• Online converters: Some online services (e.g., Zamzar, CloudConvert) may support 123 to XLS conversion, but always check privacy policies before uploading sensitive data.

Important tips

• Macros and formulas: Lotus 1-2-3 macros will not convert directly to Excel macros. Manual recreation may be necessary.
• Formatting: Some formatting and features may not transfer perfectly. Review your data after conversion.
• Backup: Always keep a backup of your original 123 files before conversion.
