How to export your library to JSON

Bulk-export your library as a .json file for scripts and other systems.

JSON is the format to pick when something other than a person is going to read the export. Every image keeps its name, URL, language and alt text together, so nothing has to be re-matched on the other end.

1

Open Export As → .json

On My Library, click Export As and pick .json in the Format row of the panel that opens.

The Export Options panel in Alt Text Studio's My Library with .json selected and outlined in red, and a Download .json button below the format row
Picking .json changes the download button to match.

Select the rows you want to export

Tick rows individually, or use the header checkbox to select every row matching your current search and filters (selection works across pages, not just the visible page). To export the whole library, clear search and filters first, then use the header checkbox.

The checkbox column of the My Library table in Alt Text Studio, with the select-all box in the header and the first row's box both outlined in red and ticked
The export acts on exactly the rows you tick.

What you get

A .json file containing one object per image, not one per language. Each object has image_name, image_url, created_at, and an alt_text object keyed by ISO 639 language code — the same shape as the JSON you see on a single image's detail page. Uploads show YOUR_IMAGE_URL_HERE in place of a public URL. The optional columns in the panel apply to CSV only; they are not added to the JSON.

Sample exported .json
[
  {
    "image_name": "headphones-product",
    "image_url": "https://alttextstudio.com/images/examples/headphones-product.webp",
    "created_at": "2026-09-01T18:24:07Z",
    "alt_text": {
      "en": "Over-ear headphones in matte black with cushioned ear pads, resting on a light gray tabletop",
      "es": "Auriculares circumaurales en negro mate con almohadillas acolchadas, sobre una mesa gris claro"
    }
  }

Large exports arrive by email

Past 500 selected items the panel switches to email mode: the button becomes Email File and a Send export to input pre-fills with your account email. The .json file arrives as an attachment from no-reply@alttextstudio.com. Rate limit: 5 export emails per 10 minutes.
