ParseAPI One or a million

One lookup.
Or a million.

Sometimes the data arrives one record at a time. Sometimes it is already a spreadsheet. Choose the way that fits your work.

SAME QUESTION. YOUR WORKFLOW.

In your app. In your file.

A date becomes a clean value in an API response, or a new column beside your original data.

Illustrative date example
Date · JavaScript SDK
import { parseAPI } from '@parseapi/sdk';

const parse = parseAPI("YOUR_API_KEY");
const result = await parse.date("08/21/2026");
console.log(result);

ONE INPUT. ONE ANSWER.

{
  "date": "2026-08-21",
  "valid": true,
  "unix": 1787270400
}
Call the API when a date arrives in your app.
