SheetReader Python Bindings

SheetReader allows to read your Excel spreadsheet files (.xlsx) blazingly fast. This repository contains the Python bindings, as the core library is implemented in C++.

Quickstart

Sheetreader is available through:

pip install pysheetreader

After successful installation, spreadsheets can be loaded:

import pysheetreader as sr
sheet = sr.read_xlsx("my_favorite_sheet.xlsx")

To convert a spreadsheet into a pandas Dataframe:

import pysheetreader as sr
import pandas as pd
sheet = sr.read_xlsx("my_favorite_sheet.xlsx")
df = pd.DataFrame.from_dict(sheet[0])

Parameters:

Build Instructions

First install the submodules, which contain the sheetreader-core dependency with:

git clone --recurse-submodules https://github.com/polydbms/sheetreader-python.git

To build from source, this repository provides a pyproject.toml. The SheetReader wheel file can be generated through:

python -m build .

or installed with pip through:

pip install .

More resources

SheetReader is part of the PolyDB Project. We also provide bindings/extensions for several other environments:

• R language: Load spreadsheets into dataframes, also available via CRAN.
• PostgreSQL FDW: Foreign data wrapper for PostgreSQL; allows to register spreadsheets as foreign tables.
• DuckDB Extension: Extension for DuckDB that allows loading spreadsheets into tables. Also available as a community extension.
