代码如下：

json2lua.py

import json
import types
import json
import os
import codecs

def space_str(layer):
    lua_str = ""
    for i in range(0,layer):
        lua_str += '\t'
    return lua_str

        if data:
            return 'true'
        else:
            return 'false'
    elif d_type is int or d_type is float:
        return str(data)
    elif d_type is list:
        lua_str = "{\n"
        lua_str += space_str(layer+1)
        for i in range(0,len(data)):
            lua_str += dic_to_lua_str(data[i],layer+1)
            if i < len(data)-1:
                lua_str += ','
        lua_str += '\n'
        lua_str += space_str(layer)
        lua_str +=  '}'
        return lua_str
    elif d_type is dict:

        data_count = 0
        for k,v in data.items():
            data_count += 1
            lua_str += space_str(layer+1)
            if type(k) is int:
                lua_str += '[' + str(k) + ']'
            else:

                if data_count < data_len:
                    lua_str += ',\n'
 
            except Exception:
                print ('error in ',k,v)
                raise
        lua_str += '\n'
        lua_str += space_str(layer)
        lua_str += '}'
        return lua_str
    else:
        print (d_type , 'is error')
        return None

def str_to_lua_table(jsonStr):
    data_dic = None
    try:
        data_dic = json.loads(jsonStr)
    except Exception:
        data_dic =[]
    else:
        pass
    finally:
        pass
    bytes = ''
    for it in dic_to_lua_str(data_dic):
        bytes += it
    return bytes

def file_to_lua_file(jsonFile,luaFile):
    with codecs.open(luaFile,"w","utf-8") as luafile:
        with codecs.open(jsonFile,"r","utf-8") as jsonfile:
            luafile.write(str_to_lua_table(jsonfile.read()))

 

测试：

test.py

import excel2json
import json2lua

jsonStr = excel2json.excel2json("./xls/test.xls","./json/test.json",1,3)
# print(jsonStr)

# print(type({}),end='\n')
# print(type([]),end='\n')
# print(type(""),end='\n')
# print(type(1),end='\n')
# print(type(1.2),end='\n')
# print(type(True),end='\n')
# print(type(False),end='\n')
# print(type(None),end='\n')
print(json2lua.str_to_lua_table(jsonStr))
json2lua.file_to_lua_file("./json/test.json","./lua/test.lua")
