I’m looking to streamline a repetitive task inside our internal backend form: at the moment I copy-paste values from multiple JSON files that sit in a Windows folder straight into the fields of that form. The goal is a small utility that reads each JSON, launches the backend webform, populates the corresponding inputs automatically, submits, and moves on to the next file until the folder is empty. Key context • Form type: an internal backend form, not a public website. • Source data: plain .json files located in a Windows directory; no API, database, or URL feed involved. What I need from you 1. A script or executable (language of your choice—Python + Selenium, Node + Puppeteer, or another proven stack) that: – Watches or iterates through the designated folder. – Parses each JSON and maps its keys to specific form fields. – Handles basic validation/error messages shown by the form. – Logs successes and any failed submissions for later review. 2. A short README explaining installation, configuration (folder path, field mappings, credentials if necessary), and how to run the automation. 3. A quick demo—screen-recording or live walkthrough—proving the tool fills at least one file end-to-end. Acceptance criteria • Every field in the form is populated with the correct value from the JSON. • The script can process a batch unattended until completion. • No hard-coded absolute paths or credentials; these must be configurable. If you’ve built similar data-entry automations before, let me know what stack you used and how you tackled login captchas or dynamic field IDs. I’m ready to test on our staging environment as soon as you deliver an initial build and will provide prompt feedback for tweaks.
