Convert IMP to 123

Understanding IMP and 123 file formats

IMP files are typically associated with Impression, a desktop publishing software for RISC OS, or sometimes with Improv, a spreadsheet application by Lotus. The 123 file format is most commonly linked to Lotus 1-2-3, a pioneering spreadsheet program. Converting between these formats is relevant when migrating data from older desktop publishing or spreadsheet applications to a more widely supported spreadsheet format.

Why convert IMP to 123?

Converting IMP to 123 is useful for users who need to access or edit their data in Lotus 1-2-3 or compatible spreadsheet software. This is especially important for legacy data preservation or for sharing files with users who only have access to spreadsheet applications.

How to convert IMP to 123

Direct conversion from IMP to 123 is not widely supported due to the rarity of both formats. However, you can use a two-step process:

1. Open the IMP file in its native application (such as Impression or Improv).
2. Export or save the file to a more common format, such as CSV or XLS, using File → Export or File → Save As.
3. Open the exported file in Lotus 1-2-3 or a compatible spreadsheet program, then save it as a 123 file using File → Save As → Lotus 1-2-3 (*.123).

Best software for IMP to 123 conversion

The best approach is to use the original software that created the IMP file. For Improv files, Lotus Improv (if available) can export to Lotus 1-2-3 format directly. For Impression files, you may need to export data as CSV and then import it into Lotus 1-2-3 or LibreOffice Calc, which can save files in the 123 format.

For users without access to legacy software, consider using LibreOffice Calc as it supports a wide range of spreadsheet formats and may help in opening intermediary formats like CSV or XLS before saving as 123.

Summary

While direct IMP to 123 conversion is rare, using export and import features in legacy and modern spreadsheet software provides a reliable workaround. LibreOffice Calc is a recommended tool for handling intermediary formats and saving to 123.
