Convert H1 to another file type
To convert H1 NMR files to another format, you need Mnova NMR or other Data software.
Convert a file to H1
To convert other file formats to the "Spectroscopy Data File" file type, you need software like Mnova NMR or a similar tool.
About H1 files
The .H1 file extension is primarily associated with Nuclear Magnetic Resonance (NMR) spectroscopy data generated by Hitachi High-Tech instruments. These files contain raw binary data representing the magnetic resonance of Hydrogen-1 nuclei, used extensively in organic chemistry to determine molecular structures. Because .H1 files are proprietary and often tied to legacy spectrometer software, researchers struggle to open them on modern personal computers without expensive licenses. Converting these files to the universal JCAMP-DX (.JDX) standard or comma-separated values (CSV) is essential for processing data in third-party tools like Mnova NMR or plotting spectra in Excel.
A secondary, less common use of the .H1 extension is for Steam Input configuration manifests. These are compressed data files used by Valve’s Steam platform to map controller inputs. Unlike the scientific data, these are internal system files and generally should not be manually converted or edited.
Convert.Guru analyzes your H1 file, detects the exact format, and lets you read the text inside.
If you want to convert H1 file to H4, B1, H11, CSV, JSON, XML, YAML, YML, TOML, INI, CFG or CONF, you can use Mnova NMR or similar software from the "NMR Spectroscopy 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 H1, try Mnova NMR or another comparable tool in the "NMR Spectroscopy Data" category.
The H1 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 H1 converter.
