NSC

This is an R package for formatting student data for the National Student Clearinghouse. The package currently supports one function: format_data().

This package is not affiliated with, endorsed by, sponsored by, or officially connected with the National Student Clearinghouse.

It prepares a seven-column student dataset for submission by creating the NSC header, detail, and trailer rows, then writing tab-delimited TXT and CSV files. Always inspect the generated files before submitting them to the National Student Clearinghouse.

format_data()

Input

• Input must contain seven columns, in this order: first name, middle initial, last name, suffix, date of birth, search date, and requester-return identifier.
• The input may be a data frame or a headerless CSV, TXT, XLS, or XLSX file.
• File inputs are read as text so leading zeros are preserved.
• Birth dates are accepted in common formats, normalized internally to yyyy-mm-dd, and written to the output as yyyymmdd.
• In-memory school_code, branch_code, and requester-return identifiers must be character values. Zeros lost before the function receives a numeric value cannot be recovered.

Output

format_data() returns a 12-column data frame containing the NSC header, student detail rows, and trailer row. It also writes one .txt file and one .csv file to file_dir. Output filenames use the current date, query option, and suffix.

Important behavior

• Punctuation is removed from every input field, including identifiers. This can change identifiers that contain punctuation.
• Birth-date values that are not recognized are rejected.
• For query option CO, multiple search dates display a message and return NULL without creating output files; use SE for multiple search dates.
• The function does not yet validate column count, query-code values, code lengths, directory existence, or all search-date formats.
• Invalid dates can produce NA comparison errors. The current number of days from the search date and today’s date must be at least 60 days. So, it gives a message if the length is 59 days or less.
• Blank names are removed, but whitespace-only names are not.
• Repeated calls using the same date, query code, and suffix overwrite files.

Example

students <- data.frame(
    first_name = "Jane",
    middle_initial = "Q",
    last_name = "Example",
    suffix = "",
    date_of_birth = "2000-01-01",
    search_date = "2020-01-01",
    requester_return_id = "0001",
    stringsAsFactors = FALSE
)

formatted <- format_data(
    school_code = "001234",
    branch_code = "00",
    school_name = "Example College",
    file_creation_date = "20260907",
    query_option = "SE",
    file_dir = tempdir(),
    input_file_name = students,
    suffix = "example"
)

The school_code, branch_code, and requester-return identifier are quoted so leading zeros remain available to the function.
