Collect Newsletter Signups and Feedback — and Query Them Like a Database

By Info2Sheets Team

Building a web form shouldn't require a backend. Querying that form's data shouldn't require an export. With Info2Sheets, you get both — out of the box.

This post walks through two real examples: a newsletter signup form and a product feedback form. For each one, you'll see how submissions land in Google Sheets and how you can immediately query that data with filters — no extra tooling required.

Why most form setups create more work than they save

The classic approach — build a server endpoint, write a database schema, wire up a CSV export — adds overhead that grows over time. Every form means another thing to maintain. Every export means another manual step.

Info2Sheets flips that model. Your HTML form submits directly to a unique endpoint. The data lands in a Google Sheet you already own. And that same data is queryable as JSON the moment it arrives.


Example 1: Newsletter Signup Form

Here's a straightforward newsletter signup form — name, email, a preferred frequency, and consent checkboxes for the privacy policy and email updates:

A visitor fills it out and hits submit. Within seconds, a new row appears in your connected Google Sheet:

No server code. No webhook configuration. No database migration. The form keeps its own design, and your sheet gets the data.

Read the data back as JSON

Once submissions are flowing in, you can read them programmatically using the authenticated data endpoint:

GET /api/forms/your-form-id/data

The response is clean JSON — one object per row, column headers as keys:

This means any internal script, cron job, or admin dashboard can pull current newsletter subscribers without touching the spreadsheet directly.

Filter newsletter data with query parameters

Suppose you capture a preferred frequency — weekly or monthly. You can filter the response on the fly:

GET /api/forms/your-form-id/data?frequency=weekly

You're not writing SQL. You're not building a reporting layer. You just pass a column name as a query parameter and get back exactly the rows you need.


Example 2: Product Feedback Form

Feedback forms usually collect more fields — rating, email, free-text comments. Here's what one looks like in practice:

After a few submissions, your Google Sheet builds up a clean, structured record of every response:

Each field maps to a column. The timestamp is always included. No setup required on the sheet side.

Read feedback as a live JSON feed

The same data endpoint works for feedback forms. Your internal tools get a live view of every response:

GET /api/forms/your-feedback-form-id/data

Use this to power a lightweight admin view, trigger follow-up logic, or feed a sentiment analysis script — all without maintaining a separate data pipeline.

Filter feedback by any column

When you need to pull a specific subset of responses — say, every 4-star review, or every entry from a particular respondent — query parameters let you slice the data instantly. Any column in the sheet can be used as a filter:

GET /api/forms/your-feedback-form-id/data?rating=4
GET /api/forms/your-feedback-form-id/data?email=john@doe.com

Filters also stack. Combine multiple parameters in a single request and the API returns only rows that match every condition:

GET /api/forms/your-feedback-form-id/data?rating=4&email=john@doe.com

Each query runs against the live sheet data, so you're always looking at current submissions — no caching, no exports, no manual refresh.

Setup takes minutes:

  1. Create a form in the Info2Sheets dashboard and connect it to a Google Sheet
  2. Point your HTML form's action attribute at your unique endpoint
  3. Share the sheet with the Info2Sheets service account
  4. Start querying submissions immediately via the data endpoint

No infrastructure. No backend code. No exports. Just your form, your sheet, and a query API that's already there.
