将数据从一个Excel工作表写入到另一个工作表

Question

I have some .csv files in my folder with names like 1filename.csv , 2filename.csv , 3filename.csv then 1abc.csv , 2abc.csv and so on.

I need to merge files with same post name and each file has same no. of columns with same heading.So final file should have only one row with titles for columns and appended with data.

Example: 1. 1filename.csv , 2filename.csv , 3filename.csv should be merged to filename.csv (where the data is appended one after the other)

2. 1abc.csv , 2abc.csv will be merged and to form abc.csv

Can I achieve this in batch file or with the help of phpexcel? I want to do in batch file but i am not sure that it is possible.

Thanks

These are the files which needs to be merged I will have 1000s of files splitted with different domains :

This is how csv files will look like, one file can have maximum of 800 rows and same number of columns with same heading:

Answer 1

Iin cmd you can use:

copy /b 1filename.csv+2filename.csv filename.csv

copy /b 1abc.csv+2abc.csv abc.csv

Answer 2

EDIT : Small bug fixed

The original code does not take into account that the file names will be processed in alphabetic order, not in post-name groups.

@echo off
setlocal EnableDelayedExpansion

rem I have some .csv files in my folder 
rem with names like 1filename.csv, 2filename.csv, 3filename.csv then 1abc.csv, 2abc.csv and so on.
set "postName="
for /F %%a in ('dir /B *.csv ^| sort /+2') do (
   rem I need to merge files with same post name
   set "name=%%a"
   if "!name:~1!" neq "!postName!" (
      set "postName=!name:~1!"
      rem and each file has same no. of columns with same heading.
      rem So final file should have only one row with titles for columns 
      echo Merging data into: !postName!
      copy "%%a" "!postName!" > NUL
   ) else (
      rem and appended with data.
      (for /F "skip=1 delims=" %%b in (%%a) do echo %%b) >> "!postName!"
   )
)

You always should post a segment of the files or describe its contents at least, otherwise we can only guess about it...

This Batch solution may fail if the files contains special Batch characters, like < > | ! < > | !

Please, note that the info in a picture can not be copy-pasted as text. You should post data as text enclosed in code tags, like this one:

C:\ dir /b
1www.ais.csv
1www.futureshade.com.au.csv
2www.ais.csv
2www.futureshade.com.au.csv
3www.ais.csv
test.bat

C:\ test
Merging data into: www.ais.csv
Merging data into: www.futureshade.com.au.csv

C:\ dir /b
1www.ais.csv
1www.futureshade.com.au.csv
2www.ais.csv
2www.futureshade.com.au.csv
3www.ais.csv
test.bat
www.ais.csv
www.futureshade.com.au.csv

Note that this solution is designed for filenames with just one digit in the first character, so it fail if there are more than 9 files in the same post name (this is the type of details that you should post since the very begining).

2ND EDIT : Output testing added

The test below show that this solution works as stated:

1www.ais.csv
