- Google Sheets R API
Google Sheets R API
Access and manage Google spreadsheets from R with
- Access a spreadsheet by its title, key or URL.
- Extract data or edit data.
- Create | delete | rename | copy | upload | download spreadsheets and worksheets.
- Upload local Excel workbook into a Google Sheet and vice versa.
googlesheets is inspired by gspread, a Google Spreadsheets Python API
The exuberant prose in this README is inspired by Tabletop.js: If you've ever wanted to get data in or out of a Google Spreadsheet from R without jumping through a thousand hoops, welcome home!
The released version is available on CRAN
Or you can get the development version from GitHub:
googlesheets is designed for use with the
%>% pipe operator and, to a lesser extent, the data-wrangling mentality of
dplyr. This README uses both, but the examples in the help files emphasize usage with plain vanilla R, if that's how you roll.
dplyr internally but does not require the user to do so. You can make the
%>% pipe operator available in your own work by loading
Function naming convention
To play nicely with tab completion, we use consistent prefixes:
gs_= all functions in the package.
gs_ws_= all functions that operate on worksheets or tabs within a spreadsheet.
gd_= something to do with Google Drive, usually has a
gs_synonym, might one day migrate to a Drive client.
Here's how to get a copy of a Gapminder-based Sheet we publish for practicing and follow along. You'll be sent to the browser to authenticate yourself with Google at this point.
gs_gap() %>% gs_copy(to = "Gapminder") ## or, if you don't use pipes gs_copy(gs_gap(), to = "Gapminder")
Register a Sheet (in this case, by title):
gap <- gs_title("Gapminder") #> Sheet successfully identified: "Gapminder"
Here's a registered

Visit a registered
googlesheet in the browser:
gap %>% gs_browse() gap %>% gs_browse(ws = "Europe")
Read all the data in a worksheet:
africa <- gs_read(gap) #> Accessing worksheet titled 'Africa'. #> No encoding supplied: defaulting to UTF-8. str(africa) #> Classes 'tbl_df', 'tbl' and 'data.frame': 624 obs. of 6 variables: #> $ country : chr "Algeria" "Algeria" "Algeria" "Algeria" ... #> $ continent: chr "Africa" "Africa" "Africa" "Africa" ... #> $ year : int 1952 1957 1962 1967 1972 1977 1982 1987 1992 1997 ... #> $ lifeExp : num 43.1 45.7 48.3 51.4 54.5 ... #> $ pop : int 9279525 10270856 11000948 12760499 14760787 17152804 20033753 23254956 26298373 29072015 ... #> $ gdpPercap: num 2449 3014 2551 3247 4183 ... head(africa) #> <tibble [6 x 6]> #> country continent year lifeExp pop gdpPercap #> <chr> <chr> <int> <dbl> <int> <dbl> #> 1 Algeria Africa 1952 43.077 9279525 2449.008 #> 2 Algeria Africa 1957 45.685 10270856 3013.976 #> 3 Algeria Africa 1962 48.303 11000948 2550.817 #> 4 Algeria Africa 1967 51.407 12760499 3246.992 #> 5 Algeria Africa 1972 54.518 14760787 4182.664 #> 6 Algeria Africa 1977 58.014 17152804 4910.417
Some of the many ways to target specific cells:
gap %>% gs_read(ws = 2, range = "A1:D8") gap %>% gs_read(ws = "Europe", range = cell_rows(1:4)) gap %>% gs_read(ws = "Africa", range = cell_cols(1:4))
readr-style control of data ingest -- highly artificial example!
gap %>% gs_read(ws = "Oceania", col_names = paste0("Z", 1:6), na = c("1962", "1977"), col_types = "cccccc", skip = 1, n_max = 7) #> Accessing worksheet titled 'Oceania'. #> No encoding supplied: defaulting to UTF-8. #> <tibble [7 x 6]> #> Z1 Z2 Z3 Z4 Z5 Z6 #> <chr> <chr> <chr> <chr> <chr> <chr> #> 1 Australia Oceania 1952 69.12 8691212 10039.6 #> 2 Australia Oceania 1957 70.33 9712569 10949.65 #> 3 Australia Oceania <NA> 70.93 10794968 12217.23 #> 4 Australia Oceania 1967 71.1 11872264 14526.12 #> 5 Australia Oceania 1972 71.93 13177000 16788.63 #> 6 Australia Oceania <NA> 73.49 14074100 18334.2 #> 7 Australia Oceania 1982 74.74 15184200 19477.01
Create a new Sheet from an R object:
iris_ss <- gs_new("iris", input = head(iris, 3), trim = TRUE) #> Warning: At least one sheet matching "iris" already exists, so you may #> need to identify by key, not title, in future. #> Sheet "iris" created in Google Drive. #> Range affected by the update: "A1:E4" #> Worksheet "Sheet1" successfully updated with 20 new value(s). #> Accessing worksheet titled 'Sheet1'. #> Sheet successfully identified: "iris" #> Accessing worksheet titled 'Sheet1'. #> Worksheet "Sheet1" dimensions changed to 4 x 5. #> Worksheet dimensions: 4 x 5.
Edit some arbitrary cells and append a row:
iris_ss <- iris_ss %>% gs_edit_cells(input = c("what", "is", "a", "sepal", "anyway?"), anchor = "A2", byrow = TRUE) #> Range affected by the update: "A2:E2" #> Worksheet "Sheet1" successfully updated with 5 new value(s). iris_ss <- iris_ss %>% gs_add_row(input = c("sepals", "support", "the", "petals", "!!")) #> Row successfully appended.
Look at what we have wrought:
iris_ss %>% gs_read() #> Accessing worksheet titled 'Sheet1'. #> No encoding supplied: defaulting to UTF-8. #> <tibble [4 x 5]> #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> <chr> <chr> <chr> <chr> <chr> #> 1 what is a sepal anyway? #> 2 4.9 3 1.4 0.2 setosa #> 3 4.7 3.2 1.3 0.2 setosa #> 4 sepals support the petals !!
Download this precious thing as csv (other formats are possible):
iris_ss %>% gs_download(to = "iris-ish-stuff.csv", overwrite = TRUE) #> Sheet successfully downloaded: #> /Users/jenny/rrr/googlesheets/iris-ish-stuff.csv
Download this precious thing as an Excel workbook (other formats are possible):
iris_ss %>% gs_download(to = "iris-ish-stuff.xlsx", overwrite = TRUE) #> Sheet successfully downloaded: #> /Users/jenny/rrr/googlesheets/iris-ish-stuff.xlsx
Upload a Excel workbook into a new Sheet:
gap_xlsx <- gs_upload(system.file("mini-gap", "mini-gap.xlsx", package = "googlesheets")) #> File uploaded to Google Drive: #> /Users/jenny/resources/R/library/googlesheets/mini-gap/mini-gap.xlsx #> As the Google Sheet named: #> mini-gap
Clean up our mess locally and on Google Drive:
gs_vecdel(c("iris", "Gapminder")) file.remove(c("iris-ish-stuff.csv", "iris-ish-stuff.xlsx"))
Remember, the vignette shows a lot more usage.

What the hell do I do with this?
googlesheets as a read/write CMS that you (or your less R-obsessed friends) can edit through Google Docs, as well via R. It's like Christmas up in here.
Use a Google Form to conduct a survey, which populates a Google Sheet.
googleformrpackage provides an R API for Google Forms, allowing useRs to POST data securely to Google Forms without authentication. On CRAN and GitHub (README has lots of info and links to blog posts).
Gather data while you're in the field in a Google Sheet, maybe with an iPhone or an Android device. Take advantage of data validation to limit the crazy on the way in. You do not have to be online to edit a Google Sheet! Work offline via the Chrome browser, the Sheets app for Android, or the Sheets app for iOS.
There are various ways to harvest web data directly into a Google Sheet. For example:
- IFTTT, which stands for "if this, then that", makes it easy to create recipes in which changes in one web service, such as Gmail or Instagram, trigger another action, such as writing to a Google Sheet.
- Martin Hawksey blog post about feeding a Google Sheet from IFTTT.
IMPORTXML(), IMPORTHTML(), IMPORTFEED(): Google Sheets offer functions to populate Sheets based on web data.
- Martin Hawksey offers TAGS, a free Google Sheet template to setup and run automated collection of search results from Twitter.
googlesheets to get all that data into R.
Use it in a Shiny app! Several example apps come with the package.
