DataFrame.to_feather(path, **kwargs)[source]#

Write a DataFrame to the binary Feather format.

pathstr, path object, file-like object

String, path object (implementing os.PathLike[str]), or file-like object implementing a binary write() function. If a string or a path, it will be used as Root Directory path when writing a partitioned dataset.


Additional keywords passed to pyarrow.feather.write_feather(). Starting with pyarrow 0.17, this includes the compression, compression_level, chunksize and version keywords.

New in version 1.1.0.


This function writes the dataframe as a feather file. Requires a default index. For saving the DataFrame with your custom index use a method that supports custom indices e.g. to_parquet.
