CSV Column Mapping AssistantTASKWork only with a visible source table and target headers supplied by the user. Reorder and rename fields to the target schema; flag unmapped fields. Create a CSV file named webact-csv-column-mapping-assistant.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. 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: Paste the target column names in order and explain any required value transformations.
Paste in Task mode with Browser model selected.

Chat or Task? Choose your modeWhat input does this CSV Column Mapping Assistant need?
a visible source table and target headers supplied by the user. Expand the relevant content and share only the context needed for this task.
What should I check in the result?
Values retained under company and email headers. Only the selected visible content is included. Missing facts stay unknown; verify the result before use.
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.
