Usage
DO NOT CREATE A NEW SCRIPT! Use the pre-installed script:
.opencode/skills/spss-file-metadata/run.sh <path_to_sav_file> [output_json_file]
Examples:
# Output to stdout
.opencode/skills/spss-file-metadata/run.sh blueprint.sav
# Save to file
.opencode/skills/spss-file-metadata/run.sh blueprint.sav metadata.json
What it does
Extracts metadata from SPSS .sav files without loading data rows (fast, memory efficient):
- Column names, labels, types, formats
- Value labels for categorical variables
- File properties (encoding, row/column counts)
- Missing value ranges
Uses pyreadstat with metadataonly=True. All dependencies pre-installed in virtual environment at .opencode/skills/spss-file-metadata/venv/.
