在python中合并json文件时出现问题

Question

I was trying to merge multiple json files with the same headers. I used the the code discussed in other posts and tweaked a bit on destination folder as follow:

  import glob
  result= []
  filepath = 'D:/Football matters/Sttratagem data access/WYScout/trial data/MergeTest'
  all_header_files = glob.glob(filepath+'/*.json')

    for f in all_header_files:
        with open(f, "rb") as infile:
            result.append(json.load(infile))

    with open("merged_file.json", "wb") as outfile:
         json.dump(result, outfile)

When I loop it to merge, it showed some error as follow:

TypeError: a bytes-like object is required, not 'str'

You can download the sample file Here .

In my case, I have 100 over json files to merge into one. Can anyone advise it how to merge?

The issue is in your usage of glob. Here's an example of its usage.

import glob
filepath = 'D:/Football matters/Sttratagem data access/WYScout/trialdata/MergeTest'
all_json_files = glob.glob(filepath+'/*.json')

You can now use a for loop as before with all_json_files
