What is an IMP file?
An .IMP file is a data container that multiple software applications use for different purposes. The most common use is a data import log file created by Tally ERP 9. However, the .IMP extension also represents older document types like the classic Improv Spreadsheet developed by Lotus, and survey data import packages.
Different Types of IMP Files
Because many developers use the .IMP extension, the internal format changes depending on the creator. Some .IMP files are plain text logs encoded in the UTF-16 (LE) format. Others are compressed ZIP archives used by the 3Shape Dental System or car navigation systems like the Hyundai Map Update Tool. The extension is also used for Hungarian tax forms (NAV ÁNYK), Sage 50 accounting data, and Mobipocket e-book source files.
How to open IMP files?
Because an .IMP file has multiple possible meanings, you need to identify its internal structure before you can read it. viewer.online/imp analyzes .IMP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it directly in your browser. This helps you determine if you are looking at a text log, a spreadsheet, or a compressed archive.
Software and tools
If your file is an accounting log, you need Tally ERP 9. If it is a classic spreadsheet, you need Lotus Improv. If you want to use the data in modern software, we recommend file conversion to sensible target formats like .CSV, .TXT, or .XLSX on convert.guru.
Summary
Because .IMP files use the known UTF-16 (LE) format or standard archive structures, viewer.online/imp can safely open and display them online, eliminating compatibility problems.
