Most Google Forms to Slack setups notify the channel on every submission. That works when volume is low, but useful alerts disappear quickly as responses grow.
A field filter adds one decision between the form and Slack. You choose a question, a condition, and a value. FormAlert evaluates each new response locally in Google Apps Script and sends a Slack message only when the rule matches.
Common examples include budget thresholds on lead forms, priority labels on support requests, and severity flags on bug reports. The team sees fewer messages, but the ones that arrive are more likely to need action.
FormAlert runs inside the Google Forms editor add-on. Webhook URLs and response values stay in your Google account. Matching notifications go directly to your Slack Incoming Webhook.
