These functions can be used to import data, from local or remote paths, or from the internet. They work closely with the certeprojects package to support Microsoft Planner project numbers. To support row names and older R versions, import_*() functions return plain data.frames, not e.g. tibbles.

)the full path of the file to be imported, will be parsed to a character, can also be a remote location (from http/https/ftp/ssh, GitHub/GitLab)
a Microsoft Planner project number
transform the imported data with auto_transform()
arguments passed on to methods
Excel sheet to import, defaults to first sheet
a cell range to read from, allows typical Excel ranges such as "B3:D87" and "Budget!B2:G14"
language of the date names, such as weekdays and months
expected date format, will be coerced with format_datetime()
expected time format, will be coerced with format_datetime()
separator for decimal numbers
separator for thousands
expected time zone
values to interpret as NA
number of first rows to skip
character to separate values in a row
columns to select, supports the tidyselect language)
use first row as header
first row to start importing
a Teams account from Azure or an AzureAuth Microsoft 365 token, e.g. retrieved with certeprojects::connect_teams()
remote location of any data set, can also be a (non-raw) GitHub/GitLab link
a full path in Teams, including the Team name and the channel name. Leave blank to use interactive mode, which allows file/folder picking from a list in the console.
Importing any unlisted filetype using import() requires the rio package to be installed.
Importing an Excel file using import_xlsx() or import_excel() requires the readxl package to be installed.
Importing an SPSS file using import_sav() or import_spss() requires the haven package to be installed.
Importing a Feather file using import_feather() requires the arrow package to be installed. Apache Feather provides efficient binary columnar serialization for data sets, enabling easy sharing data across data analysis languages (such as between Python and R). Use the col_select argument (which supports the tidyselect language) for specific data selection to improve importing speed.
Importing the clipboard using import_clipboard() requires the clipr package to be installed.
Importing mail attachments using import_mail_attachment() requires the certemail package to be installed. It calls download_mail_attachment() internally and saves the attachment to a temporary folder.
The import_url() function tries to download the file first, after which it will be imported using the appropriate import_*() function.
The import_teams() function uses certeprojects::teams_download_file() to provide an interactive way to select a file in any Team, to download the file, and to import the file using the appropriate import_*() function.
