Extract text from SDA codebooks (CDBK)
To convert CDBK Codebooks to another format, you need SDA or other Data software.
To convert other file formats to the "Survey Codebook File" file type, you need software like SDA or a similar tool.
A .CDBK file acts as a Roper Center codebook utilized primarily by the SDA (Survey Documentation and Analysis) software suite. It stores metadata, variable names, labels, and formatting instructions required to interpret raw survey dataset responses. Survey researchers rely on these files to understand what specific numeric values represent in historical polling data.
The .CDBK format is highly specialized and closed. It cannot be natively opened by common spreadsheet software like Microsoft Excel or mainstream statistical packages like IBM SPSS without specific import scripts. Relying on this format restricts data accessibility to users who have access to the original SDA environment or specific data archives. Without the accompanying raw dataset, the file only serves as a reference dictionary.
Researchers usually need to convert .CDBK files to TXT, CSV, or PDF to review the survey questions and variable coding rules independently of the dataset. Direct conversions to statistical syntax files require careful parsing to ensure no variable labels are truncated.
Standard online converters fail to process this niche data structure. Just drag and drop your file to identify the format, view it, and convert it when possible. Our platform inspects the internal text to extract the underlying variable dictionary, allowing you to bypass software restrictions.
Convert.Guru analyzes your CDBK file, detects the exact format, and lets you read the text inside.
Users also converted SAV, SPE and PHD files.
If you want to convert CDBK file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use SDA or similar software from the "Survey Dataset Metadata" 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 CDBK, try SDA or another comparable tool in the "Survey Dataset Metadata" 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 CDBK converter.
