Webpage to JSON ExtractorTASKWork only with a selected block with recurring records. Convert the requested fields into a JSON array without inventing missing values. Create a JSON file named webact-webpage-to-json-extractor.json. Keep the complete file under 48,000 UTF-8 bytes. Use only observed content and facts I supply. Keep missing values unknown. Preserve IDs, dates, units and currencies. Report omitted, truncated or unreadable content; do not claim full coverage. Verify the output against the source and stop if the required input is unavailable. Return valid JSON with documented field types; use null for unknown values when suitable. Ask me for any required settings or source facts that are missing before starting. Start with up to 25 records or one short document. Report exactly which source content was included. Setup: List the JSON fields you need and how to represent missing values.
Paste in Task mode with Browser model selected.
Make it yours. List the JSON fields you need and how to represent missing values.
Before you start.
Two objects; second date is null.
Chat or Task? Choose your modeWhat input does this Webpage to JSON Extractor need?
a selected block with recurring records. Expand the relevant content and share only the context needed for this task.
What should I check in the result?
Two objects; second date is null. Only the selected visible content is included. Missing facts stay unknown; verify the result before use.
Does this collect a whole website?
Work with a small selection on the tab you activate. Hidden records, linked pages and content that has not loaded are outside this recipe. Select a readable region and check the exported coverage.
Can I use this on the Free plan?
Yes. Install the Chrome extension, verify your WebAct account and use an available ChatGPT browser connection in the same Chrome profile. Free includes 25 user-started automation tasks per calendar month (UTC), shared across all tools. A task counts when its first action starts; steps and necessary retries within that task do not count separately. Provider limits apply. After 25 tasks, upgrade or wait for the reset.
Does this page run the task?
This page provides an illustrative example and a task to copy. Run it through WebAct on the source page you activate. Selected page context is processed by your browser AI provider. An ordinary answer in browser Chat uses no WebAct automation allowance; creating a file or changing fields in Task mode does.
