docxtractr is an R package for extracting tables & comments out of Word documents (docx). Development versions are available here and production versions are on CRAN.
Microsoft Word docx files provide an XML structure that is fairly straightforward to navigate, especially when it applies to Word tables. The docxtractr package provides tools to determine table count, table structure and extract tables from Microsoft Word docx documents.
Many tables in Word documents are in twisted formats where there may be labels or other oddities mixed in that make it difficult to work with the underlying data. docxtractr provides a function—assign_colnames—that makes it easy to identify a particular row in a scraped (or any, really) data.frame as the one containing column names and have it become the column names, removing it and (optionally) all of the rows before it (since that's usually what needs to be done).
The following functions are implemented:
read_docx: Read in a Word document for table extractiondocx_describe_tbls: Returns a description of all the tables in the Word documentdocx_describe_cmntss: Returns a description of all the comments in the Word documentdocx_extract_tbl: Extract a table from a Word documentdocx_extract_cmnts: Extract comments from a Word documentdocx_extract_all: Extract all tables from a Word document (deprecated)docx_tbl_count: Get number of tables in a Word documentdocx_cmnt_count: Get number of comments in a Word documentassign_colnames: Make a specific row the column names for the specified data.frame
