Before you start

Open the tool in a current browser. The demonstrated operation runs locally on your device and needs no account or credits. Use the public example values below.

Step-by-step instructions

  1. Open the tool using the button next to the video. Keep the default mode unless the next step specifies a different one.
  2. Enter Apple, Banana and Apple on separate lines; keep line input and JSON-array output, then press Convert list.
  3. Inspect the result shown below the inputs. If the tool has an action button, press it after editing; live converters update as you type.
  4. Copy or export the result using the controls provided by this tool. Check the output before using it in another application.
  5. Choose duplicate-removal and sorting options deliberately. CSV values containing commas need proper quoting.

On a computer

Use the keyboard to enter the example values. Review the options, then inspect the output and use Copy or an export action when available.

On a phone

Tap the input field and enter the example. Close the on-screen keyboard to review the options and result; keep the tab open until you finish.

In Safari on iPhone, open the sharing menu and choose Save to Files if the result opens in a new tab. In Android Chrome, check Downloads. Keep this tab open until processing finishes.

For a better result

Choose duplicate-removal and sorting options deliberately. CSV values containing commas need proper quoting.

Questions and troubleshooting

Does this demonstration use my real data?

No. The recording uses public example values created for the guide. The service operates on the input you enter in your own browser.

What should I check before relying on the result?

Choose duplicate-removal and sorting options deliberately. CSV values containing commas need proper quoting.

If you see a message that the service is overloaded, wait and try again later. A failed attempt does not mean that your source file has changed.
