Regex by Example | Free AI tool

A Better Regex Generator

Give AI an example and tell AI what you want, then generate code in which language you selected.
You can run the code immediately!

Works with CSV Input

You can use csv as input, just like:

Year,Make,Model,Description,Price
1997,Ford,E350,"ac, abs, moon",3000.00
1999,Chevy,"Venture ""Extended Edition""","",4900.00
1999,Chevy,"Venture ""Extended Edition, Very Large""","",5000.00
1996,Jeep,Grand Cherokee,"MUST SELL!
air, moon roof, loaded",4799.00

And tell AI what you want:

the model cheaper than 4800

Then you can get the regex and code:

const regex = /[^,\n]+,[^,\n]+,[^,\n]+,[^,\n]+,(\d+\.\d+)/g;
const matchModelCheaperThan4800 = [];
let match;

while ((match = regex.exec(data)) !== null) {
  if (parseFloat(match[1]) < 4800) {
    matchModelCheaperThan4800.push(match[0]);
  }
}

console.log(matchModelCheaperThan4800);

Support Different Language

I had add 5 languages:

• JaveScript
• TypeScript
• C/C++
• JAVA
• Rust

Don't be afraid that the language you used is not supported, just say to AI:

Give me an kotlin example.

then you can get the code in your language

fun main() {
    val data = """
        1997,Ford,E350,"ac, abs, moon",3000.00
        1999,Chevy,"Venture ""Extended Edition""","",4900.00
        1999,Chevy,"Venture ""Extended Edition, Very Large""","",5000.00
        1996,Jeep,Grand Cherokee,"MUST SELL!
        air, moon roof, loaded",4799.00
    """.trimIndent()
    
    val regex = Regex("[^,\n]+,[^,\n]+,[^,\n]+,[^,\n]+,(\\d+\\.\\d+)")
    val matchModelCheaperThan4800 = mutableListOf<String>()

    regex.findAll(data).forEach {
        if (it.groupValues[1].toFloat() < 4800) {
            matchModelCheaperThan4800.add(it.value)
        }
    }

    for (match in matchModelCheaperThan4800) {
        println(match)
    }
}

It works!
