ComponentsDocument loadersGoogle DriveOn this pageGoogle DriveGoogle Drive is a file storage and synchronization service developed by Google.This notebook covers how to load documents from Google Drive. Currently, only Google Docs are supported.Prerequisites​Create a Google Cloud project or use an existing projectEnable the Google Drive APIAuthorize credentials for desktop apppip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib🧑 Instructions for ingesting your Google Docs data​By default, the GoogleDriveLoader expects the credentials.json file to be ~/.credentials/credentials.json, but this is configurable using the credentials_path keyword argument. Same thing with token.json - token_path. Note that token.json will be created automatically the first time you use the loader.The first time you use GoogleDriveLoader, you will be displayed with the consent screen in your browser. If this doesn't happen and you get a RefreshError, do not use credentials_path in your GoogleDriveLoader constructor call. Instead, put that path in a GOOGLE_APPLICATION_CREDENTIALS environmental variable.GoogleDriveLoader can load from a list of Google Docs document ids or a folder id. You can obtain your folder and document id from the URL:Folder: https://drive.google.com/drive/u/0/folders/1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5 -> folder id is "1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5"Document: https://docs.google.com/document/d/1bfaMQ18_i56204VaQDVeAFpqEijJTgvurupdEDiaUQw/edit -> document id is "1bfaMQ18_i56204VaQDVeAFpqEijJTgvurupdEDiaUQw"pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlibfrom langchain.document_loaders import GoogleDriveLoaderloader = GoogleDriveLoader(    folder_id="1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5",    token_path='/path/where/you/want/token/to/be/created/google_token.json'    # Optional: configure whether to recursively fetch files from subfolders. Defaults to False.    recursive=False,)docs = loader.load()When you pass a folder_id by default all files of type document, sheet and pdf are loaded. You can modify this behaviour by passing a file_types argument loader = GoogleDriveLoader(    folder_id="1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5",    file_types=["document", "sheet"],    recursive=False)Passing in Optional File Loaders​When processing files other than Google Docs and Google Sheets, it can be helpful to pass an optional file loader to GoogleDriveLoader. If you pass in a file loader, that file loader will be used on documents that do not have a Google Docs or Google Sheets MIME type. Here is an example of how to load an Excel document from Google Drive using a file loader. from langchain.document_loaders import GoogleDriveLoaderfrom langchain.document_loaders import UnstructuredFileIOLoaderfile_id = "1x9WBtFPWMEAdjcJzPScRsjpjQvpSo_kz"loader = GoogleDriveLoader(    file_ids=[file_id],    file_loader_cls=UnstructuredFileIOLoader,    file_loader_kwargs={"mode": "elements"},)docs = loader.load()docs[0]You can also process a folder with a mix of files and Google Docs/Sheets using the following pattern:folder_id = "1asMOHY1BqBS84JcRbOag5LOJac74gpmD"loader = GoogleDriveLoader(    folder_id=folder_id,    file_loader_cls=UnstructuredFileIOLoader,    file_loader_kwargs={"mode": "elements"},)docs = loader.load()docs[0]Extended usage​An external component can manage the complexity of Google Drive : langchain-googledrive
It's compatible with the ̀langchain.document_loaders.GoogleDriveLoader and can be used
in its place.To be compatible with containers, the authentication uses an environment variable ̀GOOGLE_ACCOUNT_FILE` to credential file (for user or service).pip install langchain-googledrivefolder_id='root'#folder_id='1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5'# Use the advanced version.from langchain_googledrive.document_loaders import GoogleDriveLoaderloader = GoogleDriveLoader(    folder_id=folder_id,    recursive=False,    num_results=2,  # Maximum number of file to load)By default, all files with these mime-type can be converted to Document.text/texttext/plaintext/htmltext/csvtext/markdownimage/pngimage/jpegapplication/epub+zipapplication/pdfapplication/rtfapplication/vnd.google-apps.document (GDoc)application/vnd.google-apps.presentation (GSlide)application/vnd.google-apps.spreadsheet (GSheet)application/vnd.google.colaboratory (Notebook colab)application/vnd.openxmlformats-officedocument.presentationml.presentation (PPTX)application/vnd.openxmlformats-officedocument.wordprocessingml.document (DOCX)It's possible to update or customize this. See the documentation of GDriveLoader.But, the corresponding packages must be installed.pip install unstructuredfor doc in loader.load():    print("---")    print(doc.page_content.strip()[:60]+"...")Customize the search pattern​All parameter compatible with Google list()
API can be set.To specify the new pattern of the Google request, you can use a PromptTemplate().
The variables for the prompt can be set with kwargs in the constructor.
Some pre-formated request are proposed (use {query}, {folder_id} and/or {mime_type}):You can customize the criteria to select the files. A set of predefined filter are proposed:
| template                               | description                                                           |

| gdrive-query-in-folder                 | Search query in folder_id (and sub-folders if recursive=true)  |

This field can be used to memorize a summary of the document or others indexed tags (See method lazy_update_description_with_summary()).If you use the mode="snippet", only the description will be used for the body. Else, the metadata['summary'] has the field.Sometime, a specific filter can be used to extract some information from the filename, to select some files with specific criteria. You can use a filter.Sometimes, many documents are returned. It's not necessary to have all documents in memory at the same time. You can use the lazy versions of methods, to get one document at a time. It's better to use a complex query in place of a recursive search. For each folder, a query must be applied if you activate recursive=True.import osloader = GoogleDriveLoader(                gdrive_api_file=os.environ["GOOGLE_ACCOUNT_FILE"],                num_results=2,                template="gdrive-query",                filter=lambda search, file: "#test" not in file.get('description',''),                query='machine learning',                supportsAllDrives=False,                )for doc in loader.load():    print("---")    print(doc.page_content.strip()[:60]+"...")PreviousGoogle Cloud Storage FileNextGrobidPrerequisites🧑 Instructions for ingesting your Google Docs dataPassing in Optional File LoadersExtended usageCustomize the search patternAdvanced usage
