He is asking for converting that into XML I will just create an another table out of this Database and convert and post it over there, simple jSon would have been better but he is saying he doesn't know

Sounds like he needs to start learning how to do his job ... :sigh:

Store the data as a CSV text file; Excel opens it as a single sheet workbook.

Here's a suggestion; tell him to learn. JSON isn't complex; it is textbased, human readable, with plenty of tools. My first was DBaseIV. Would you convert all to DBaseIV format if I told you JSON is too complicated?

Send him back, he does not know how to do the job you hired him for! Calling himself a developer is disingenuous.

No I didn't hire him, I neither have authority to hire him my friend

But yes I did send him the jSon now we are trying to write a generic SQL Query to read from jSon string instead of conversions, then he wanted me to help him in that I am trying using OpenjSon, do you know any idea how to read through jSon string which has objects embedded within other objects. Any idea you have my friend.

Hi I have a table which has 100s of 1000s of records

huge json string.

Excel limits. 32k maximum size for a cell 1,048,576 maximum rows 16,384 columns Excel specifications and limits - Excel[^] If you already have a 200,000 rows then a reasonable growth estimate would mean your solution would need to support 2,000,000 rows. And that is not going happen in excel. You didn't define 'huge' nor what is in that json has but see the cell size limit and column limit. Again if you are already pushing those then growth would suggest you will exceed it.

Is this a one time job? On demand? Once a day? Once a minute? That will impact what is reasonable in terms of how long you your job can take processing this.

Is that the only problem that it is json? Basically the acronym 'ETL' exists for this very thing. So why not do the following 1. Create another database, do not try to do this in the existing one. 2. Create a job that incrementally processes the rows and flattens outs the data into the new database. 3. Then the other person uses that database, with the data nicely parsed out to do what they want. How to flatten it out? Well if the data is nice and stable then you could just create a table with the columns named appropriately. If however the json is includes lots of depth and is dynamic then you will need to create a metadata solution such as a table that stores a name, and type, and perhaps another table with values. The types allows you to handle arrays and other embedded types (circular). Keeping in mind that this problem is one you would have needed to deal with an the Excel idea any ways. This also allows the data to be kept up to date. Then it is up to them, not you, how often to actually pull the data.
