Period Comparison ReportTASKWork only with a small table displaying two explicitly labelled periods. Calculate differences with approved page code and explain them without invented causes. Create a CSV file named webact-period-comparison-report.csv. Keep the complete file under 48,000 UTF-8 bytes. If required, propose a read-only run_js inspection of the current document for my explicit approval. Do not fetch URLs, access credentials, execute remote code or change page content. 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. Explicit reference periods and numbers required. Zero denominators and mismatched units need clear handling. 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: Label the two periods and clarify the baseline for percentage changes. Flag a zero baseline.
Paste in Task mode with Browser model selected.
Make it yours. Label the two periods and clarify the baseline for percentage changes. Flag a zero baseline.
Before you start.
Difference plus 20; percentage change plus 20 percent.
Chat or Task? Choose your modeWhat input does this Period Comparison Report need?
a small table displaying two explicitly labelled periods. Expand the relevant content and share only the context needed for this task.
What should I check in the result?
Difference plus 20; percentage change plus 20 percent. Explicit reference periods and numbers required. Zero denominators and mismatched units need clear handling.
Can it read every chart and hidden metric?
Use readable values and explicit reporting periods. Canvas-only charts, unloaded data and missing definitions are excluded. Keep currencies separate and do not infer causes from changes alone.
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.
