JS: How to convert string to JSON Format using replace and then JSON.Parse

Question

I am having trouble converting my string to JSON format.

I have this specific kind of string:

{Object1=Text Goes Right Here, and Here, Object2 = Another Text Here}

I wanted to convert it to something like this

{"Object1":"Text Goes Right Here, and Here", "Object2":"Another Text Here"}

Can anybody help me figure out how to properly convert this.

I tried using replaceAll but it keeps on breaking on the comma.

str.replaceAll('=', '":"').replaceAll(', ', '", "').replaceAll('{', '{"').replaceAll('}', '"}')

And it ended up like this.

{"Object1":"Text Goes Right Here", "and Here", "Object2":"Another Text Here"}

I also tried regexm but it is not replacing the actual strings.

/[^[a-zA-Z]+, [a-zA-Z]+":$']/g

A regex or anything that could help would be fine. Thank you in advance!

is that really what your initial string looks like? That's not valid anything. Can you show what it actually looks like? — Kinglish

@Kinglish yes, that was the actual string I am getting from the result. I find it weird but I need to find a workaround just to format my object in proper JSON format. — Ayuk

can we depend on the equal sign only happening with the assignments (Object1 = ...)? — Kinglish

Using Positive Lookahead

https://regex101.com/r/iCPrsp/2

const str = '{Object1=Text Goes Right Here, and Here, Object2 = Another Text Here}'

const res = str
  .replaceAll(/,\s*(?=[^,]*=)/g, '", "')
  .replaceAll(/\s*=\s*/g, '":"')
  .replaceAll('{', '{"')
  .replaceAll('}', '"}')

console.log(JSON.parse(res))

I made you an ugly script to fix an ugly problem... ;)

let string = "{Object1=Text Goes Right Here, and Here, Object2 = Another Text Here}";

let stringSplitted = string.replace(/[\{\}]/g,"").split("=")
console.log("=== Step #1")
console.log(stringSplitted)

let keys = []
let values = []
stringSplitted.forEach(function(item){
  item = item.trim()
  keys.push(item.split(" ").slice(-1).join(" "))
  values.push(item.split(" ").slice(0,-1).join(" "))
})
console.log("=== Step #2")
console.log(keys, values)

keys.pop()
values.shift()
console.log("=== Step #3")
console.log(keys, values)

let result = {}
keys.forEach(function(key, index){
  result[key] = values[index]
})
console.log("=== Result")
console.log(result)
