Posted on by BhagvanReddy1

Hi Everyone,

I need help to convert string to Table format, I have a list which is storing last modified values. So i am fetching values against each item, string is in following format

"[{\"Change Date\":\"2023-01-28\",\"Change Field\":\"Description\",\"Previous Value\":\"123 Abcdefghi\",\"Changed Value\":\"123 Abcdefghij1\",\"Who Performed\":\"User1\"}]

[{\"Change Date\":\"2023-01-28\",\"Change Field\":\"Description\",\"Previous Value\":\"123 Abcdefghij1\",\"Changed Value\":\"123 Abcdefghij12\",\"Who Performed\":\"User2\"}]

[{\"Change Date\":\"2023-01-28\",\"Change Field\":\"Description\",\"Previous Value\":\"123 Abcdefghij12\",\"Changed Value\":\"123 Abcdefghij123\",\"Who Performed\":\"User 3\"}]

[{\"Change Date\":\"2023-01-28\",\"Change Field\":\"Title\",\"Previous Value\":\"12abcdefgh\",\"Changed Value\":\"12abcdefgh1\",\"Who Performed\":\"User 1\"}]"

Change Date	Field	Previous values	Changed Values	Modied
2023-01-28	Description	123 Abcdefghi1	123 Abcdefghij12	User 1
2023-01-28	Description	123 Abcdefghi	123 Abcdefghi1	User 2

Tried with split & forall functions but didn't succeed. Can someone help me?.

Thanks 🙂

@BhagvanReddy1 ,

Sunday morning and noting more productive to do, so I built a model and the this works in my test

With( { wTable: Substitute( Substitute( Substitute( Substitute( Substitute( Substitute( Substitute( Substitute( Substitute( YourTextHere, "{", "" ), "}", "" ), "\", "" ), "", "" ), "", "" ), """", "" ), Char(10) & Char(10), "|" ), "[", "" ), "]", "" ) }, ShowColumns( AddColumns( Split( wTable, "|" ), "Change Date", Last( Split( Index( Split( Result, "," ).Result, 1 ).Result, ":" ) ).Result, "Change Field", Last( Split( Index( Split( Result, "," ).Result, 2 ).Result, ":" ) ).Result, "Previous Value", Last( Split( Index( Split( Result, "," ).Result, 3 ).Result, ":" ) ).Result, "Changed Value", Last( Split( Index( Split( Result, "," ).Result, 4 ).Result, ":" ) ).Result, "Who Performed", Last( Split( Index( Split( Result, "," ).Result, 5 ).Result, ":" ) ).Result ), "Change Date", "Change Field", "Previous Value", "Changed Value", "Who Performed" ) )

and in case you are wondering, you cannot create field names dynamically.

Thanks 😃 for the quick reply, whereas above functionality will return single value of it in table format. where as it should return multiple values.

ClearCollect(colTable,

Char(10) & Char(10),
"|"
),
"[",

},

@BhagvanReddy1 ,

I assume you have sorted this - my model below with the input (from a field in my test list) at the top and the output at the bottom.

@BhagvanReddy1 ,

I will give you a clue which I will help if you do not find it - I simply copied the code from your post and worked with that. Have a look at the difference in spacing between records on what you have posted now and what I copied (it is in the top of my solution post) - there is only one thing you need to change.

I found it there was space in between each array element, apart from that didn't find anything, Is that the one?

When I copied your code from your Post, there was a line between each of the records, meaning two hard returns

Char(10) & Char(10)

which I then replaced with a pipe | which is used as the delimiter between the records

Char(10) & Char(10), "|"

and then to split them

Split( wTable, "|" )

So whatever is between your records (I suspect a single Char(10) ) needs to go in the second code above.
