Example 1: Changing the word "work" to "play" and then changing "welcome" to "Hello there!". Copy and paste the following into editor box and click Save

{
  "name": "My Regex Test 1",
  "tags": "regex test",
  "description": "My first test of creating regex",
  "regexes": [
      {
          "find": "Online Tools",
          "replace": "CRAZY FOOLS"
      },
      {
          "find": "welcome",
          "replace": "HELLO THERE!"
      }
  ]
}

Example 2: This example uses regex capture groups. Change anything between '---' to '<<<' and '>>>'.

{
  "name": "My Regex Test 2",
  "tags": "regex test",
  "description": "My first test of creating regex",
  "regexes": [
      {
          "find": "<*h1[^>]*>(.*?)<*/*h1>",
          "replace": ""
      },
      {
          "find": "---(.*)---",
          "replace": "<<< $1 >>>"
      }
  ]
}
