Create spreadsheets & documents with Java

Create a shareable spreadsheet from Java using the built-in java.net.http.HttpClient (Java 11+) — no Apache POI, no Google API. Send your rows as JSON and read the URL back. Works in plain Java, Spring Boot services, and Android backends.

import java.net.URI;
import java.net.http.*;

var json = """
{
  "title": "Q3 Revenue",
  "sheets": [{ "rows": [
    ["Month", "Revenue", "Growth"],
    ["July", 48200, "+12%"]
  ] }]
}
""";

var req = HttpRequest.newBuilder()
    .uri(URI.create("https://openofficeai.com/api/v1/sheets"))
    .header("Authorization", "Bearer YOUR_API_KEY")
    .header("Content-Type", "application/json")
    .POST(HttpRequest.BodyPublishers.ofString(json))
    .build();

var res = HttpClient.newHttpClient()
    .send(req, HttpResponse.BodyHandlers.ofString());
System.out.println(res.body()); // contains the "url"
