Converty JSON to Array in fastest way


Recommended Posts

I am looking for way to convert json data into array in fastest way. I guess this could be done using regex.

This is my sample of json data:

Quote

        {
            "invoice_id": 28532595,

and I want to convert it into array with this structure:

Yes, but wondering if you even tried to look for the answer yourself before dumping the question here as there are several JSON udfs available?

Yes I tried Json UDF and I can parse the json data into array but it takes too long time. My json files are large and I am trying to save some time. I think regex could be much faster to parse this data but I don't know to write the regex pattern. This is why I am looking for help in forum.

So what about being way more specific and tell us what you have done, how long it takes now, post an example JSON file  etc etc etc .... 
It seriously can't be that hard to provide enough details so people can really help you and is it not like you are new around here.

Thinking of faster json data parsing came up to my mind when I discovered that large files can be loaded to array very fast. I recently discovered function  _FileReadToArray which can load 1MB csv report file into array in less than 1second. Wondering now if I can achieve similar result with json data parsing.

At this moment I use JSON.au3 UDF downloaded from here:

Quote

There is not much code I use. I simply read json string into variable and then decode it. Then I use Json_ObjGet function to get needed data

Local $sJson = FileRead("test.json")
Local $oJson = Json_Decode($sJson)
Local $a_oJson = Json_ObjGet($oJson , "invoices")

for $i=0 to Ubound($a_oJson) - 1
    if Json_ObjGet(a_oJson[$i], "invoice_id") = "123" then MsgBox(0,0,1)
next

I just checked the time needed to parse the json data and result says that Json_Decode() function need 17.6seconds to load 1.7MB JSON file in my PC. I belive I can load the data faster. Or maybe I am wrong?

Maybe something along those lines ?

#include <Constants.au3>
#include <Array.au3>

Local $sJson = FileRead("Test.txt")
Local $aArray = StringRegExp($sJson, '("invoice_id"|"order_id"|"series_id"): (\d+)', 3)

_ArrayDisplay($aArray)

I need to install some component to make it work, right?

After some modification I have this code:

#include "Array.au3"

$json = FileRead("test.json")

;Local $aArray = StringRegExp($json, '"(.*)": (\[[^[]+]|[^,]+)', 4)
Local $aArray = StringRegExp($json, '"(.*)": ("([^""]+)"|\[[^[]+]|[^,]+)', 4)

_ArrayDisplay($aArray)

for $I=0 to Ubound($aArray) - 1
    _ArrayDisplay($aArray[$i])
Next

test.json:

Indeed, you want and array of invoices, each entry having an array of items.

You can load such a JSON data into an SQLite table using the json1 extension. From there it's easy to navigate, select, compute, change, remove thanks to SQLite power. You can as well build a table of invoices and a linked table of sold items.

Given that Amazon JSON uses a defined format for all invoices, things are pretty trivial.

The provided sample is malformed for a strict JSON parser.

The original sample JSON was not malformed for a strict JSON parser.  It met all JSON formatting standards.  You only modified one line and that modification had nothing to do with strict-formatting.  The data may be bad, but it is strictly-formatted.

You changed:

"ean": "123123123aa",

to

"ean": "123123123",

Both values are strings, so it made no difference as it relates to strictly-formatted JSON?

 

Edit:

I see that you must have been referring to the last sample that was supplied.  As I stated, I was referring to the original sample that was posted.

Highlighted that I referred to the original post's JSON, not the last sample.

Doesn't it lack a closing bracket?

It contains a list of unnammed invoices. Turning that list into an array removes the need to give each a name (a different name, that is, for strict JSON).

Yes. 

For JSON it is free as far as I remember.
