Abstract - In recent timesduetotechnologicaladvances the
need to improve the existing system of processes is greater
than ever before. Also, with data-driven decision-making
processes that come into play the need to integrate that with
the process helps business and management in making the
right decision that benefits everyone. This paper focuses on
automating existing processes using Python as a translation
method, understanding datathushelpingdecision-drivenData
by highlighting issues and providing details in data analysis.

1. INTRODUCTION
1.1 Data Analysis
Data analysis is the process of evaluating, cleaning,
modifying, and modeling data for the purpose of obtaining
useful information, informing conclusions, and supporting
decision-making. Data analysis has many features and
methods, which include different strategies under different
terms, andare used in different domains of business,science,
and social sciences. In today's business world, data analysis
plays a key role in making the decisions more scientific and
helps businesses more efficient. [4]
1.2 Business Analysis
Business Statistics (BA) refers to the skills, expertise, and
processes of repeated evaluation and past business
performance research to gainan understandingandadvance
business planning. Business statistics focus on developing
new data and understandingbusiness performancebasedon
data and statistical methods. In contrast, business acumen is
traditionally focused on using a consistent set of metrics to
both measure previous performance and direct business
planning. In other words, business intelligence focuses on
definition, whereas business analysis focuses on physician
prediction and writing. [3]
1.3 Python for Automation
The most important skills for business analysts in
consultation with executives, bank investments, and many
other analytics activities (usually at least traditionally) were
Excel and PowerPoint. many have become very visible in
recent years. The data and its complexity are growing
exponentially, requiringadvanceddataprocessingtoolssuch
as programming languages. In this article, the emphasis is on
Python and how it works, and why we believe it is an
important skill right now for the future. [1][2]
2. LITERATURE SURVEY
Nikita Khudov [1] describes few characteristics why one
should opt for automation using python for performing the
business analysis. The idea is to demonstratecertain metrics
that gives python the upper hand for better decision making
and time saving techniques.
sayoneadmin [2] describes the business analytics trends
that are go hand in hand with python to give us the best fit to
help us analyze the data and make decisions out of it.
Business analysis [3] is the expert advice of identifying
business needs and finding solutions to business problems.
Solutions often involve part of software development, but
mayalsoincludeprocessdevelopment,organizationalchange
or strategic planning and policy development.
Data analysis [4] has many features and methods, which
include different strategies under different names, and are
used in different domains of business. There are various
processes within it ranging from data requirements, to its
cleaning, testing and modeling.
3. PROPOSED SYSTEM
The proposed system will help userstoupload,download
data using python as a tool, analyzing data to provide
information that can help the business team make decisions
to benefit the most from it. We can alsostore data indifferent
repositories and create different dashboards to present data
in a more informative way. Ultimately it will helpsave alotof
time, effort and risk of human error in order to provide
solutions.

4. METHODOLOGY
While testing the performance on data analytics using
tools such as excel and python, I tested the functionality in
the following parameters:
4.1 The Amount of data that can be handled
We have used different sets of data with different values
to test the performance of both excel and python. In small
databases both are advanced,andpythonworksveryfastand
does not slow down. But when the no. of lines goes over 1 lac
line objects is when the excelstarts toloosenthesmoothness
and firmness of the software comes into play. We can also
add a database at the end of the python code to save data for
future use and usage.
4.2 Doing Analysis
In the second step, weused a few data sets to perform the
analysis based on a few steps. It can be done in both Excel
and python. But with excel the user should have some
knowledge of the UI and where each functionresidesandcan
later filter data by using shortcut keys to filter data. But with
python this process is much easier because the coding
language is easier to understand, and the implementation is
easier.
Following functionalities were tested in both excel and
python:
A. Loading the data from different sources
1. In excel, we must repeat the import steps for
each new data source needed for analysis, which
over time does not provide easy import of data
from multiple sources (this can be achieved
using Power Query in Excel)
2. Whereas in python, it only one step that can be
inserted inside the code with the location of the
new source and then the code can
simultaneously import data from multiple
sources
B. Filtering data on certain criteria
1. In excel, we can filter data on various terms, but
it takes time to add terms and filter data from
time to time
2. Whereas in python, we can add many conditions
and convert data in a matter of seconds and then
compare data using data frames in python
C. Finding duplicates from the dataset basedonspecific
criteria
1. In excel, it is possible to find duplicates, but it
takes 2-3 different steps based on the concept to
identify duplicate data and filter that in the final
data.
2. Even in python, a single line of code can help
detect and remove duplicates.Inthiscasewecan
say the diagnostic parameter, which data we
should keep and thus removeother line/linesof
duplicate data.
D. Changing the data format of individual cellorcolumn
to a particular format
1. In excel, it is sometimes very difficult to change
the cell format of the value you want. Also, if the
data is left unchanged then it may affect the
analysis
2. Whereas in python, after the process flow is set
and encoded. Conversion will happen
automatically, and the conversion type is also
very fast thus speeding up the whole process
E. Merging data from two or more datasets at a same
time
1. In excel, we use lookup functions to combine
data from two different sets based on common
parameters. Post that we need to make changes
by saving the lookup data as values to create
additional lookups
2. While in python, we just need to specify a join
type (like SQL query) and python will do
everything else. The performance while
performing joins - the speed it is very fast even
on large databases

4.3 Scalability & Future use
In more recent times, with new technologies being added
to everyday processes, using python not only provides an
easy-to-use method but also helps to balance performance
based on changing trends. With the support of huge
community and new libraries added like ML, AI we can use
that to analyze data and predict output. Since Big Data is
already in use, we can use ML / AI to process historical data
and predict a business-benefit outcome.
4.4 Dashboards & Displaying outputs
Recent trenddashboardsareusedtodisplayoutputbased
on analytics. Dashboards can be created on both excel and
python. An added benefit of creatingadashboardinpythonis
that we can use various JavaScript libraries to present the
output in a highly informative way. We just need to link the
input data with the correct ID and the dashboards are
automatically created in the front part of the web app.
4.5 Data Integrity & Safety
Another advantage of using pythoniskeepingdata(raw+
analyzed) in a secure database for future use. When we use
this practice, we are able to maintain the integrity of the data
and avoid the risk of violating the privacy of our data by not
sharing data with anyone not involved in the process. With
excel it is possible that the data may be corrupted,orthedata
may fall into the wrong hands that can allbeavoidedbyusing
python and database in an end-to-end process.
4.6 Easy of Access & Real Time Sharing
With the concept of centralized data and real-time
sharing, data is updated simultaneously as webapp, and
python will be connected to the same database. It is also easy
to share as users can be anywhere in the world and a
mapping is created while a project is created in a web
application.
5. RESULT
Based on the analysis and evaluation of end-to-end
performance, we have come to understand that the use of
python as an automated method of creating webapps is
superior, helpful and in recent times very useful to drive the
whole process, it also uses data more efficiently and provide
information based on current trends and business needs.
