data transformer

help you prepare your csv data file(s)

convertor

convert json to csv

rjj c

select a json file in the current directory, choose to enter another file name (don't need the extension) for output or not (Y/n); if not, the converted csv will be saved with the same name as the json♻

reversor

reverse csv back to json

rjj r

select a csv file in the current directory, choose to enter another file name for output or not (Y/n); if not, the converted json file will be saved with the same name; 🌀support any data type, even emoji🐷

converter

convert csv to json

rjj y

fix the reversor invisible special char assigned to 1st column name issue; but in return without emoji support

cluster

convert csv to json with cluster layer

rjj z

at least two columns in the selected csv file; column 2 should contain clustered data, i.e., a,b,c

eraser

erase duplicate record(s) 🧽

rjj e

remove repeated row(s) for a selected csv file

join 🖇

join all csv(s) together (repeated records accepted)

rjj join

pure join; will not create identifier(s); differ from jointer below

inner join 🖇

inner join two csv files

rjj i

join record(s) based on identical value(s) in 1st column

outer join 🖇

outer join two csv files

rjj o

join record(s) based on value(s) in 1st column; identical value(s) will be overlapped

detector

detect the co-existing record(s) between two csv files📃🔍📃

rjj d

select two csv files to execute the detection process, then give a name for the output file; co-existing record(s) will be indicated in a newly created column Coexist

filter

locate the input Keyword among all csv files in the current directory👁‍🗨 (and could opt to expand to its all sub-folder files; cool right?)🔍

rjj f

source file (location info) will be indicated in a newly created first column Source_file; the exact coordinate (x,y) will be given in the newly created second and third columns, namely Column_y and Row_x; and the full record will be pasted behind for simplifying your auditing work 📑

matcher

identify matched/repeated record(s)📃📃🔍 among all csv in the current directory and extend to its sub-directories📁

rjj m

provide a name to the output file (if not, the output file will be named as output.csv); source file (location) will be indicated in a newly created column Source_file

uniquer

identify unique/non-repeated record(s)🔍📃 among all csv in the current directory and extend to its sub-directories📁

rjj u

give a name to the output file; source location will be indicated in a newly created column Source_file

binder

bind all csv files together by columns in the current directory

rjj b

binder is different from jointer below; it can be considered as a horizontal merge whereas jointer is for vertical merge (basically by rows)

jointer and splitter 📌✂️

joint or split your data file(s)

jointer

joint all csv files in the current directory together🖇

rjj j

all file names will be stored in the first field of the newly created column File; when you execute the command you will be asked for assigning a name for the output file

splitter

split the selected csv file to different csv files and name it according to the value in the first field of that selected file📑

rjj s

extension for excel

extended function/module(s) for handling excel file(s)

xplit

split the selected excel (.xls or .xlsx) to pieces and name it according to the value in the first field of that selected excel

rjj x

joint

joint all excels (.xls and .xlsx) in the current directory together; all file names will be stored in the first field of the newly created column File

rjj t

differ from csv jointer, since both .xls and .xlsx is accepted, and the file extention will not be taken, it will be merged while two of them share the same file name (cannot be split by the command above); understand this condition, make good use of it! 🙌

matxh

identify matched/repeated record(s)🔍 in the current directory and extend to its sub-directories; for excel

rjj h

source file (location) will be indicated in a newly created column Source_file; the exact sheet name inside that file will be told in another newly created column Sheet_name

uniquex

identify unique/non-repeated record(s)🔍 in the current directory and extend to its sub-directories; for excel

rjj q

source will be indicated in a newly created column Source_file; exact sheet will be told in Sheet_name

kilter

locate the input Keyword among all excel files (.xls and .xlsx) in the current directory (and could expand to its sub-folders)👁‍🗨

rjj k

this feature is similar to the csv filter; but since each excel file is possible to contain more than one sheet📄, the sheet number will be stored in the newly created column Sheet_z, then the exact coordinate (x,y) will be given after it, namely Column_y and Row_x; and the full record will be pasted behind as well; super kooooo 🍻
