Extract text from RETScreen projects (RS1)
To convert RS1 projects to another format, you need RETScreen Expert or other Spreadsheet software.
To convert other file formats to the "Energy Analysis Data" file type, you need software like RETScreen Expert or a similar tool.
The .RS1 file is a proprietary project document created by RETScreen, a clean energy management software used by engineers to evaluate the financial and technical viability of energy projects.
While early versions of RETScreen functioned as standard macro-enabled XLS workbooks, the platform evolved into a standalone application that uses specialized formats like .RS1 and .RETX. These files store massive amounts of complex data, including facility metrics, climate benchmarks, energy models, and lifecycle financial risk assessments.
The main disadvantage of the .RS1 format is its rigid, closed ecosystem. While RETScreen Expert offers a free "Viewer" mode, users face a paywall (an expensive annual subscription) to actually save, print, or export their own data. If you receive an .RS1 file but lack the paid software, standard tools like Microsoft Excel or Google Sheets cannot open it. This makes sharing critical financial models with stakeholders or external clients incredibly frustrating.
To make this data useful, the ideal conversion targets are XLSX for raw tabular data, CSV for database import, or PDF for fixed-layout reporting. However, because the format relies on complex internal calculation engines and proprietary databases, standard online converters completely fail to process it. Our tool will analyze the file's internal structure and identify any embedded, supported formats. While full mathematical conversion is impossible outside of the original software, we can inspect the file, extract raw text, and help you recover trapped information whenever possible.
Convert.Guru analyzes your RS1 file, detects the exact format, and lets you read the text inside.
Users also converted PLMA, ZEX and TOAD files.

To convert files to RS1, try RETScreen Expert or another comparable tool in the "Clean Energy Project Feasibility" category.
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 RS1 converter.
