Batch parses .twb and .twbx files and returns migration-oriented
inventory tables. The summary table is one row per workbook; detail tables
retain workbook identity so they can be filtered or joined downstream.
Usage
audit_tableau_folder(
path,
recursive = TRUE,
pattern = NULL,
write_csv = FALSE,
output_dir = NULL
)Arguments
- path
Folder containing Tableau workbooks, or a character vector of
.twb/.twbxfiles.- recursive
Logical; search folders recursively. Default
TRUE.- pattern
Optional regular expression applied to file basenames.
- write_csv
Logical; write each returned table as a CSV file. Default
FALSE.- output_dir
Directory for CSV output when
write_csv = TRUE.
Value
A named list with class twbparser_audit containing:
- workbooks
One row per parsed workbook with counts and migration complexity flags.
- datasources
Datasource inventory across parsed workbooks.
- calculated_fields
Calculated field complexity across workbooks.
- field_usage
Worksheet field usage across workbooks.
- lineage_edges
Combined lineage edge table across workbooks.
- issues
Files that could not be parsed and their error messages.
Examples
demo <- system.file("extdata", package = "twbparser")
