By default, uploaded files are limited to 200MB. You can configure this using the ``server.maxUploadSize`` config option. For more info on how to set config options, see https://docs.streamlit.io/develop/api-reference/configuration/config.toml Parameters ---------- label : str A short label explaining to the user what this file uploader is for. The label can optionally contain GitHub-flavored Markdown of the following types: Bold, Italics, Strikethroughs, Inline Code, Links, and Images. Images display like icons, with a max height equal to the font height. Unsupported Markdown elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g., ``"1\. Not an ordered list"``. See the ``body`` parameter of |st.markdown|_ for additional, supported Markdown directives. For accessibility reasons, you should never set an empty label, but you can hide it with ``label_visibility`` if needed. In the future, we may disallow empty labels by raising an exception. .. |st.markdown| replace:: ``st.markdown`` .. _st.markdown: https://docs.streamlit.io/develop/api-reference/text/st.markdown type : str or list of str or None Array of allowed extensions. ['png', 'jpg'] The default is None, which means all extensions are allowed. accept_multiple_files : bool If True, allows the user to upload multiple files at the same time, in which case the return value will be a list of files. Default: False key : str or int An optional string or integer to use as the unique key for the widget. If this is omitted, a key will be generated for the widget based on its content. No two widgets may have the same key. help : str or None A tooltip that gets displayed next to the widget label. Streamlit only displays the tooltip when ``label_visibility="visible"``. If this is ``None`` (default), no tooltip is displayed. The tooltip can optionally contain GitHub-flavored Markdown, including the Markdown directives described in the ``body`` parameter of ``st.markdown``. on_change : callable An optional callback invoked when this file_uploader's value changes. args : tuple An optional tuple of args to pass to the callback. kwargs : dict An optional dict of kwargs to pass to the callback. disabled : bool An optional boolean that disables the file uploader if set to ``True``. The default is ``False``. label_visibility : "visible", "hidden", or "collapsed" The visibility of the label. The default is ``"visible"``. If this is ``"hidden"``, Streamlit displays an empty spacer instead of the label, which can help keep the widget alligned with other widgets. If this is ``"collapsed"``, Streamlit displays no label or spacer. Returns ------- None or UploadedFile or list of UploadedFile - If accept_multiple_files is False, returns either None or an UploadedFile object. - If accept_multiple_files is True, returns a list with the uploaded files as UploadedFile objects. If no files were uploaded, returns an empty list. The UploadedFile class is a subclass of BytesIO, and therefore is "file-like". This means you can pass an instance of it anywhere a file is expected. Examples -------- Insert a file uploader that accepts a single file at a time: >>> import streamlit as st >>> import pandas as pd >>> from io import StringIO >>> >>> uploaded_file = st.file_uploader("Choose a file") >>> if uploaded_file is not None: ... # To read file as bytes: ... bytes_data = uploaded_file.getvalue() ... st.write(bytes_data) >>> ... # To convert to a string based IO: ... stringio = StringIO(uploaded_file.getvalue().decode("utf-8")) ... st.write(stringio) >>> ... # To read file as string: ... string_data = stringio.read() ... st.write(string_data) >>> ... # Can be used wherever a "file-like" object is accepted: ... dataframe = pd.read_csv(uploaded_file) ... st.write(dataframe) Insert a file uploader that accepts multiple files at a time: >>> import streamlit as st >>> >>> uploaded_files = st.file_uploader( ... "Choose a CSV file", accept_multiple_files=True ... ) >>> for uploaded_file in uploaded_files: ... bytes_data = uploaded_file.read() ... st.write("filename:", uploaded_file.name) ... st.write(bytes_data) .. output:: https://doc-file-uploader.streamlit.app/ height: 375px ) r`rarCrdrfrhrjrlr^r_r:)r_file_uploader) rGr`rarCrdrfrhrjrlr^r_r:r(r(r.rqs)r_r^r:r:ScriptRunContext | Nonec  Cs"t|}t|j||dddt|| td|t|j||||d} |r't|}t} | | _|| _ |dur6|ng| j dd<t d| _ || _t|j| _| | _t| | j_|dur^t|| _t|}t| j||||j|j| dd}|jd| t|jtrdSt|jtrdd |jDS|jS) NF) default_valuewrites_allowedrq)user_keyform_idr`rarCrfzserver.maxUploadSizefile_uploader_state_value)on_change_handlerrjrl deserializer serializerr: value_typecSsg|] }t|ts|qSr()rNrr+r(r(r.r/sz4FileUploaderMixin._file_uploader..)rrdgrrr r FileUploaderProtoidr`rar get_optionmax_upload_size_mbmultiple_filesr|r^rr_valuerrfrArrJrW_enqueuerNrrO)rGr`rarCrdrfrhrjrlr_r^r: element_idfile_uploader_protoserde widget_stater(r(r.rw}sh      z FileUploaderMixin._file_uploaderr"cCs td|S)zGet our DeltaGenerator.r")r)rGr(r(r.rs zFileUploaderMixin.dg)NNNNN)r`rFrarbrCrcrdrerfrgrhrirjrkrlrmr^rBr_rr&rn)FNNNNN)r`rFrarbrCrsrdrerfrgrhrirjrkrlrmr^rBr_rr&rt)r`rFrCrcrarbrdrerfrgrhrirjrkrlrmr^rBr_rr&rn)r`rFrCrsrarbrdrerfrgrhrirjrkrlrmr^rBr_rr&rt)NFNNNNN)r`rFrarbrCrBrdrerfrgrhrirjrkrlrmr^rBr_rr&rv)r`rFrarbrCrBrdrerfrgrhrirjrkrlrmr_rr^rBr:rxr&rv)r&r") rXrYrZr rqrrwpropertyrr(r(r(r.r\s    " Qr\)r$r%r&r')< __future__r dataclassesrtextwraprtypingrrrrr typing_extensionsr streamlitr *streamlit.elements.lib.file_uploader_utilsr !streamlit.elements.lib.form_utilsr streamlit.elements.lib.policiesrrstreamlit.elements.lib.utilsrrrrrstreamlit.proto.Common_pb2rrLrUploadedFileInfoProto streamlit.proto.FileUploader_pb2rrstreamlit.runtime.metrics_utilrstreamlit.runtime.scriptrunnerrrstreamlit.runtime.staterrrr'streamlit.runtime.uploaded_file_managerrr collections.abcr!streamlit.delta_generatorr"rOr#r[r@rAr\r(r(r(r.s>             "$
