sas7bdat-overview

Summarize SAS7BDAT coverage by register, period, and variable availability.

Install (wheel)

Build a wheel locally and upload to your PyPI mirror:

python -m pip install maturin
maturin build --release

The wheel will be under target/wheels/.

Usage

Basic metadata-only scan (fast):

sas7bdat-overview /path/to/sas/files --out-dir /path/to/output

Include per-variable value profiles (slower, scans all rows):

sas7bdat-overview /path/to/sas/files --out-dir /path/to/output --profile

Include unique person/family counts (slower, scans all rows):

sas7bdat-overview /path/to/sas/files --out-dir /path/to/output --compute-ids

Restrict to specific registers (case-insensitive):

sas7bdat-overview /path/to/sas/files --registers lpr_diag,ind

Outputs

When --out-dir is set, the tool writes:

• register_inventory.csv — register coverage (first/last year, file count, column count)
• variable_coverage.csv — variable coverage by register and year
• variable_profile.csv — per-variable missingness and ranges (only populated if --profile is used)
• inventory_summary.md — human-readable summary table

The JSON output (--output) includes the full raw summaries.

File naming

Handles filenames like:

• <register>.sas7bdat
• <register><year>.sas7bdat
• <register><year><month>.sas7bdat
• <register>_YYYY_MM.sas7bdat
• <register>-YYYY-MM.sas7bdat

Register names may include underscores.
