Contact List DeduplicatorTASKWork only with a small visible contact table. Create a cleaned CSV using the user's duplicate key and preserve a duplicate-review report. Create a CSV file named webact-contact-list-deduplicator.csv. 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. No deletion from the original app. Conflicting records remain visible for human resolution. Keep one header row, consistent columns, escaped quotes and literal spreadsheet-safe text. 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: Choose an exact duplicate key and explain how conflicting notes should be retained.
Paste in Task mode with Browser model selected.
Make it yours. Choose an exact duplicate key and explain how conflicting notes should be retained.

Chat or Task? Choose your modeIs there a ready-made task in the extension?
Yes. Open Library → Examples and choose “Contact duplicate review”. Supply any requested inputs, choose the source area and review the task before running it.
Which part of the workflow does WebAct perform?
Group a small supplied contact list by an explicit exact-match key; retain conflicting names and notes in a separate CSV. This browser recipe does not include: Incoming webhooks, enrichment, CRM upserts, deleting/merging records and adding contacts to campaigns.
What input does this Contact List Deduplicator need?
a small visible contact table. Expand the relevant content and share only the context needed for this task.
What should I check in the result?
One grouped identity; both notes preserved for review. No deletion from the original app. Conflicting records remain visible for human resolution.
Will it overwrite my source data?
These recipes produce a separate file. They preserve the source and flag ambiguous values for review. Supply the matching key, locale or formatting rule when the job requires one.
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.
Workflow reference: Zapier template or automation listing. WebAct provides the scoped browser task described above.
