How to Use This Calculator

  1. Enter your Input String in the text area. This is the string you want to split.
  2. Specify the Separator that separates elements in your string. Common examples include:
    • Comma (,): For CSV data like "apple,banana,cherry"
    • Space (" "): For space-separated values like "hello world"
    • Colon (:): For key-value pairs like "key1:value1|key2:value2"
    • Pipe (|): For separating records like "record1|record2|record3"
  3. (Optional) Set a Limit to maximum number of elements to return.
  4. (Optional) Check Remove Empty Strings if you want to exclude empty elements from the result.
  5. Click the Calculate button to process the string.

Advanced Usage: Multiple Separators

If you need to split by multiple separators, enter them separated by commas in the separator field. For example, to split by comma or semicolon, enter ",;". The calculator will then use a regular expression to match any of these separators.

Example Scenarios

1. Splitting CSV Data

Input: "apple,banana,cherry"
Separator: ", "
Result: ["apple", "banana", "cherry"]

2. Parsing Space-Separated Values

Input: "hello world from calculator"
Separator: " "
Result: ["hello", "world", "from", "calculator"]

3. Splitting by Multiple Delimiters

Input: "key1:val1|key2:val2;key3:val3"
Separator: ":|;"
Result: ["key1", "val1", "key2", "val2", "key3", "val3"]
