Column moved while merge excel files?
Question:
I tried to merged all excel files and all of them only contain 1 column. However, the merged data was moved the next column. Does anyone know how to fix that?
Here is the Python code:
import glob
import pandas as pd
file_path = "c:merge-excel"
files = (file_path+"/*.xlsx")
all_files = glob.glob(files)
merged_data = pd.concat([pd.read_excel(a) for a in all_files])
merged_data.to_excel (file_path+"/Merged_files.xlsx", index=False, encoding='utf-8-sig')
file 1.xlsx:
1
2
3
4
5
6
7
file 2.xlsx:
8
9
10
11
12
13
14
15
file 3.xlsx:
16
17
18
19

Merged_files.xlsx:

Answers:
Your issue is that the default value of the header parameter to read_excel is 0, which means it is taking the first row in each excel file and using it as a column header. So you have 3 columns 1, 8, and 16 which were the first row’s value in each file. Use
pd.read_excel(a, header=None)
to work around this.
