Introduction
ejc-cli
, the first three letters of which consist of the initialsexcel
,json
orjs
,cli
.
Our projects sometimes save on back-end development costs by storing some data directly locally in json
or js
files and then using that data for rendering. But when we have more data, maintaining a lengthy json
or js
file can be laborious, and these files can only be propagated among developers.
To solve these pain points, using excel to manage our data is a great option.
excel allows for a more visual and organised way of collecting and managing our data than a json
or js
file. So we can use excel to collect the data we want, and then use the ejc-cli
tool to export the json
files that developers use.
One of the great benefits of this is that not only is it easier to manage the data, but it is no longer restricted to the developers, as non-developers can use excel to distribute it. This also makes it much more efficient and enhances collaboration between different people.
Quick start
1. Installation tools
npm i ejc-cli -g
2. Get the template excel file
You don't need to make an excel sheet yourself, a template excel file is already made here, you just need to execute:
ejc-cli gt
Or save the template file to the specified directory:
ejc-cli gt './xlsx_template/'
This will give us access to an excel template file, then just replace the data in it with what you want, yes it's that simple.
3. Exporting json
files
You can go to the Explanation module for a better understanding of
-k
,-s
Setting
-k
,-s
output using the global methodIf you have more than one
sheet
in your excel file and they have a similar structure (like the twosheets
in thetemplate.xlsx
file), then you can simply set:ejc-cli -i './xlsx_template/template.xlsx' -k 'order, title, date, director, genre, cast, money' -s 3 -n 'movieData, songData'
In this case,
ejc-cli
will read the data fromrow 3
of allsheets
and thekey
values of all the outputjson
data will beorder, title, date, director, genre, cast, money
.Set
-k
,-s
output separatelyIf you have more than one
sheet
in your excel file, and eachsheet
does not always start reading data fromline 3
, and eachsheet
does not always have the samekey
value, then you can use the "|
" splitter:ejc-cli -i './xlsx_template/template.xlsx' -k 'order, title, date | num, song_title, artist' -s '3 | 4' -n 'movieData, songData'
In this case,
ejc-cli
will read the data of the firstsheet
starting fromline 3
, and thejson
data key value of the firstsheet
will beorder, title, date
.ejc-cli
will read the data of the secondsheet
starting fromline 4
, and thejson
data key values of the secondsheet
arenum, song_title, artist
Notice
Here are the following caveats in use.
When generating
json
data, make sure that the value of-s
is correct.-s
means that the data is read from the first row of eachsheet
, the default isrow 3
.When the number of
-k
values is set to less than the number of columns in thesheet
, it will render with the number of-k
valuesYou can try running the following command to see the difference in the output data
ejc-cli -i '. /xlsx_template/template.xlsx' -k 'order, title' -n 'movieData, novelData'
The output of the
json
data is onlyorder
andtitle
values

Explanation
We can look at the structure of the obtained template excel file (template.xlsx
):
The overall structure of the table is generally divided into three blocks (top
, middle
, bottom
).
- The first block, which we call (
T
), refers to the broad heading of the entire table - The second, which we call (
M
), is an overview of the information in each column of the table and is also used to set the correspondingkey
value (-k 'order, title, date, director, genre, cast, money'
) - The third block, which we will call (
B
), is the number of rows in which the program will start reading data (-s 3
)
How to use your own excel sheet
Because everyone's production of excel is different, we strongly recommend that you use our template excel file (template.xlsx
) to manage your data, but this file may not always be styled to suit you.
So if you want to DIY
the style of your table, according to the analysis of the Explanation module, the following rules need to be followed when DIY
ing your table:
- The
T
andM
modules are not required, but please ensure that the data in your excel file, has the same structure as theB
module in the above diagram - Please ensure that your
-s
values are correct
