Convert TAB to 123

Understanding TAB and 123 file formats

TAB files are commonly used for storing tabular data, often in a plain text format where columns are separated by tab characters. These files are widely used for data exchange between spreadsheet and database applications.

123 files are associated with Lotus 1-2-3, a pioneering spreadsheet application developed by Lotus Software. The 123 format is a proprietary binary file format used to store spreadsheet data, formulas, and formatting.

Why convert TAB to 123?

Converting a TAB file to 123 format is useful when you need to work with tabular data in Lotus 1-2-3 or share data with users who rely on this legacy spreadsheet software. The conversion ensures compatibility and preserves spreadsheet features.

How to convert TAB to 123

Since Lotus 1-2-3 is no longer actively developed, direct conversion tools are rare. However, you can use intermediary software to achieve this conversion:

1. Open the TAB file in Microsoft Excel or LibreOffice Calc. Both programs can import tab-delimited files easily.
2. Save or export the file in Lotus 1-2-3 format:
• In Microsoft Excel: Go to File → Save As, then select Lotus 1-2-3 (*.wk1, *.wk3, *.wk4) as the file type. Note: Newer versions of Excel may not support this format, so Excel 2003 or earlier is recommended.
• In LibreOffice Calc: Go to File → Save As, and choose Lotus 1-2-3 (*.123) as the file type.
3. Check the converted file in Lotus 1-2-3 or compatible software to ensure data integrity.

Best software for TAB to 123 conversion

The most reliable software for this conversion is LibreOffice Calc, as it supports both importing TAB files and exporting to the 123 format. LibreOffice is free, open-source, and available for Windows, macOS, and Linux.

Alternatively, Microsoft Excel 2003 or earlier versions can be used if available, as they offer built-in support for Lotus 1-2-3 formats.

Summary

To convert a TAB file to 123 format, use LibreOffice Calc or an older version of Microsoft Excel. Import the TAB file and save it as a Lotus 1-2-3 file. This ensures your tabular data is accessible in legacy spreadsheet environments.
