Extract text from Rave reports (NDR)
To convert NDR reports to another format, you need Nevrona Rave Reports or other Page Layout software.
To convert other file formats to the "Compiled Report File" file type, you need software like Nevrona Rave Reports or a similar tool.
The .ndr extension primarily belongs to compiled report documents generated by Nevrona Rave Reports, a visual reporting add-on historically bundled with Embarcadero Delphi and C++Builder. It is also utilized by ComponentAce ReportPrinter. These files store the final, non-editable output of database queries formatted for printing or viewing.
Typically, you need the original Delphi application that generated the report or a standalone Rave Reports viewer to open them. Less commonly, .ndr files represent noise dosimeter data logs from Svantek hardware or engraving designs from Gravograph.
The primary disadvantage of the .ndr format is its severe lack of portability. It is a highly proprietary, legacy format tied to specific software ecosystems. Users cannot open .ndr files in standard web browsers, mobile devices, or modern office suites without the original generating tool. Sharing these files with clients or colleagues almost always results in them being unable to read the data.
To make the data accessible, conversion is mandatory. For archiving and universal sharing, convert .ndr to PDF to preserve the exact visual layout. For data extraction and editing, convert to CSV or DOCX.
Convert.Guru analyzes your NDR file, detects the exact format, and lets you read the text inside.
Users also converted DOCUMENTO DE NATHAN, PDF, PRN, JPG, 1, NDF, TXT, ZIP, PRNX, MKS, CRDOWNLOAD, FP3 and IS2 files.
If you want to convert NDR file to PDF, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use Nevrona Rave Reports or similar software from the "Compiled Report Document" 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 NDR, try Nevrona Rave Reports or another comparable tool in the "Compiled Report Document" 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 NDR converter.
