Excel spreadsheets made easy through Pandas magic

Project description

# XLLink for Pandas

Quick-start: https://0hughman0.github.io/xl_link/quickstart.html

Installation: `pip install xl_link`

XLLink aims to provide a powerfull interface between Pandas DataFrames, and Excel spreadsheets.

XLLink tweaks the DataFrame.to_excel method to return its own XLMap object.

This XLMap stores all the information about the location of the written DataFrame within the spreadsheet.

By allowing you to use Pandas indexing methods, i.e. loc, iloc, at and iat. XLLink remains intuitive to use. But instead of returning a DataFrame, Series, or scalar, XLMap will instead return the XLRange, or XLCell corresponding to the location of the result within your spreadsheet.

Additionally XLMaps offer a wrapper around excel engines (currently supporting xlsxwriter and openpyxl) to make creating charts in excel far more intuitive. Providing a DataFrame.plot like interface for excel charts.

## Chart demo

creating a complex chart is as easy as:

>>> f = XLDataFrame(index=('Breakfast', 'Lunch', 'Dinner', 'Midnight Snack'),
                    data={'Mon': (15, 20, 12, 3),
                          'Tues': (5, 16, 3, 0),
                          'Weds': (3, 22, 2, 8),
                          'Thur': (6, 7, 1, 9)})
>>> xlmap = f.to_excel('Chart.xlsx', sheet_name="XLLinked", engine='openpyxl')
>>> xl_linked_chart = xlmap.create_chart('bar', title="With xl_link", x_axis_name="Meal", y_axis_name="Calories", subtype='col')
>>> xlmap.sheet.add_chart(xl_linked_chart, 'F1')
>>> xlmap.writer.save()

Producing this chart:

## Formatting demo

Applying conditional formatting to a table is as easy as:

>>> import numpy as np
>>> xy_data = XLDataFrame(data={'Y1': np.random.rand(10) * 10,
                                'Y2': np.random.rand(10) * 10})
>>> xlmap = xy_data.to_excel("ConditionalFormatting.xlsx", engine='xlsxwriter')
>>> xlmap.sheet.conditional_format(xlmap.data.range, # position of data within spreadsheet
                                   {'type': '3_color_scale',
                                    'min_type': 'num', 'min_value': xlmap.f.min().min(), 'min_color': 'green',
                                    'mid_type': 'num', 'mid_value': xlmap.f.mean().mean(), 'mid_color': 'yellow',
                                    'max_type': 'num', 'max_value': xlmap.f.max().max(), 'max_color': 'red'})
>>> xlmap.writer.save()
