Today I'll show you a Microsoft Excel
0:02
clone editor that I developed directly
0:04
in the browser. So I have also deployed
0:06
this tool on the website as well. I've
0:08
also given the link in the description
0:10
of this video. So this is the actual
0:13
interface which looks something like
0:14
this. So once whenever you land on this
0:17
you have this alert message. Would you
0:19
like to start with a new blank
0:21
spreadsheet? So once you click okay that
0:24
Excel file will automatically be created
0:26
for you. So now we have interface of
0:30
similar Microsoft Excel as you can see
0:32
right here. So here you can fill out the
0:35
data that you want to do. So it's very
0:38
simple right here.
0:41
So you can basically fill out some
0:42
sample data here.
0:47
So after filling it out, you also have
0:49
the download button as well. So once you
0:51
click the download button, that Excel
0:52
file will get downloaded and
0:55
automatically saved right here. So you
0:56
can see the Excel file is automatically
0:58
created for you and uh it's very easy.
1:01
So I entirely built in this project in
1:03
HTML, CSS and JavaScript. So I've given
1:08
the link in the description of this
1:10
video. So this is the project here. It's
1:13
having a single index HTML file right
1:15
here. And as you can see uh it's round
1:18
about uh 700 lines of code. So the link
1:23
is given you can directly purchase the
1:25
full source code. So after you purchase
1:27
it, you will get the source code from
1:29
Google drive and uh it's very easy to
1:32
run this project. You come to VS code
1:34
and open this project inside local
1:37
server. So once you open this
1:40
the interface will looks similar to
1:43
this. So again you fill out the sample
1:46
data
1:49
and also if you have an existing Excel
1:52
file as well we also given this option
1:54
open file option. So click that button
1:57
and if you already have some Excel file
2:00
that you want to edit you can load that
2:02
file and automatically all the data will
2:05
get loaded here. You will see these are
2:07
the column names. These are the
2:09
different rows. You can modify this or
2:12
add some additional data. It's very
2:14
simple. So it will save you a lot of
2:17
time because no longer you don't need to
2:20
use Microsoft Excel. Instead you can use
2:22
this web application which is uh
2:24
completely free fast offline which runs
2:28
entirely in the browser. So again you
2:30
click download button and everything
2:32
will be updated for you as you can see
2:35
that. So
2:37
if you don't have Microsoft Excel, no
2:39
problem. You can purchase this web
2:41
application that I developed. The link
2:43
is given in the description. Definitely
2:46
check out the demo before purchasing it.
2:48
I've given it at the check out page. So
2:51
there is no problem in getting to the
2:53
demo. So it's entirely as you can see in
2:57
VS Code, it's entirely built in HTML,
2:59
CSS and JavaScript. And for this we are
3:02
using this XLS library which is
3:05
completely open source which is a
3:09
JavaScript based library for editing
3:11
Excel files directly in the browser.
3:15
So this is the it's also called as sheet
3:17
gs. It's also having this node package
3:21
as well. As you can see the command is
3:23
very simple npmix xls to install this.
3:27
It's having almost 5 million downloads.
3:31
So we are using this. So very simple but
3:34
yet powerful application. So here you
3:37
can just see it also shows you
3:39
additional information. How many sheets
3:41
you are creating, how many cells,
3:44
4x3 all all of these you can do this.
3:48
And if you want to create a new Excel
3:50
file, you click the new button and right
3:53
here you can
3:56
fill out whatever data you can do this.
3:59
You can just see here. So how fast and
4:01
easy it is.
4:05
So it's entirely a single page
4:07
application. All the processing happens
4:08
directly in the browser. So no
4:10
serverside code is involved. So the
4:12
application is really fast. So whenever
4:15
you try this it will also be really fast
4:17
inside your laptop or computer as well.
4:20
So
4:22
so definitely try this. I've given the
