Extract text from ISR files
To convert your ISR file to another format, you need Microsoft Excel or other Data software.
To convert other file formats to the "Invoice Status Report" file type, you need software like Microsoft Excel or a similar tool.
The .ISR file extension presents a unique challenge because it serves two completely unrelated but critical functions in business environments.
For educational service providers and school districts, an .ISR file is an Invoice Status Report generated by the Universal Service Administrative Company (USAC). These files contain vital financial data regarding E-Rate funding, specifically tracking the status of FCC Forms 472 and 474.
The Problem: While these files act as official notifications, they are often formatted as raw, pipe-delimited text files without a native association to spreadsheet software. Users frequently try to double-click them only to be met with an "Unknown File Type" error or a jumbled text stream in Notepad.
The Solution: To make this data usable for accounting and reconciliation, users should convert or import .ISR files into Microsoft Excel or Google Sheets. This allows the raw data to be filtered, sorted, and saved as standard XLSX or CSV formats.
For IT support teams, an .ISR file is a proprietary Session Recording created by ISL Online remote desktop software. These files document remote support sessions for auditing and training purposes.
The Problem: Because the format is highly optimized and proprietary, .ISR video files cannot be played in standard media players like VLC Media Player or Windows Media Player. This is a key problem when trying to share support evidence with clients or managers who do not have the ISL software installed.
The Solution: You must use the specific ISL Player utility to open the file and export it to a standard video format like AVI. Once in AVI format, the video can be further converted to MP4 for web sharing or archiving.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ISR converter.
