To convert other file formats to the "Simulation Data File" file type, you need software like PV*SOL or a similar tool.
About HOR files
A .HOR file primarily stores solar analysis horizon data, defining shading and horizon obstruction profiles for photovoltaic yield simulations. It is heavily utilized by professional solar engineering software such as PV*SOL and RADIANCE. Alternatively, the extension is used for geomagnetic observatory data formatted to the IAGA-2002 standard by INTERMAGNET, or for proprietary horoscope charts generated by Placidus astrology software. These files present significant workflow challenges. Most .HOR files are plain-text but use rigid, proprietary column structures that lock your data into a specific software ecosystem. Sharing a raw .HOR file with a client is pointless because they lack the expensive, niche applications required to interpret the obstruction data. Cross-compatibility is also poor; a horizon file exported from Solargis often requires manual reformatting before another solar engine can import it. To make this data universally accessible, you must convert it. For data science, plotting, and spreadsheet analysis, convert .HOR to .CSV or .XLSX. For archiving or sharing visual reports with clients, convert the rendered charts to .PDF. Drag and drop your file here to analyze and convert it - free, online, and without installing software.
Convert.Guru analyzes your HOR file, detects the exact format, and lets you read the text inside.
If you want to convert HOR file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use PV*SOL or similar software from the "Solar Horizon Obstruction Data" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to HOR, try PV*SOL or another comparable tool in the "Solar Horizon Obstruction Data" category.
The HOR Converter Story
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 HOR converter.
