Quick overview This workflow collects a business card photo/scan through an n8n form, uses LDX hub AnalyzeDoc (Gemini) to extract contact details as structured JSON, and appends the resulting fields as a new row in Google Sheets. How it works Receives a business card file upload (PDF/JPG/PNG) through an n8n form submission. Sends the uploaded file to LDX hub AnalyzeDoc using the Gemini model and a fixed schema prompt to extract contact fields as JSON. Parses the extracted JSON into individual fields like name, company, email, phone numbers, and address. Appends the extracted fields as a single new row in the selected Google Sheets worksheet. Setup Install the community node n8n-nodes-ldxhub and add an LDXhub API credential with your API key. Add a Google Sheets OAuth2 credential and select the target spreadsheet and worksheet in the append step. Create (or match) a header row in your sheet for full_name, job_title, company, department, email, phone, mobile, address, website, notes so the auto-mapping writes to the correct columns.

Quick overview This workflow collects an invoice PDF or image through an n8n form, uses LDX hub AnalyzeDoc (Gemini) to extract key invoice fields as JSON, and appends the results as a new row in Google Sheets. How it works Receives an invoice file upload (PDF/JPG/PNG) through an n8n form submission. Sends the uploaded document to LDX hub AnalyzeDoc (google/gemini-3.5-flash) with a prompt that extracts invoice metadata, parties, dates, and amounts into a JSON schema. Parses the extracted JSON into structured fields for downstream use. Appends the extracted invoice fields as a new row in the selected Google Sheets spreadsheet and worksheet. Setup Install the community node package n8n-nodes-ldxhub and create an LDXhub API credential (API key) for the AnalyzeDoc node. Add a Google Sheets OAuth2 credential and select the target spreadsheet and sheet in the Google Sheets append step. Create a header row in your Google Sheet that matches the extracted fields (invoice_number, issue_date, due_date, vendor_name, vendor_address, vendor_tax_id, bill_to, subtotal, tax, total, currency, payment_terms) so auto-mapping writes to the correct columns.
Extract meeting decisions and action items with LDX hub (Gemini) and Google Sheets
Quick overview This workflow collects a meeting-minutes PDF via an n8n form, uses LDX hub (Gemini) to segment it by agenda and extract decisions and action items, then appends each item as a row in Google Sheets. How it works Receives a PDF upload through an n8n form submission trigger. Sends the document to LDX hub AnalyzeDoc (Google Gemini) to split the minutes into agenda-topic segments and return them as structured JSON — a topic that spans multiple pages stays in one segment. Converts the agenda segments into a JSONL batch so each segment can be processed independently. Sends the batch to LDX hub StructFlow (Google Gemini) to extract every decision and action item with owner and due date per agenda segment. Expands the extracted results into one row per decision/action item with agenda context. Appends the rows to a selected Google Sheets worksheet. Setup Install the n8n-nodes-ldxhub community node and create an LDXhub API credential. Create a Google Sheet with columns: agenda_no, agenda_title, item_type, item, owner, due_date. Add a Google Sheets OAuth2 credential and select the target spreadsheet and sheet in the append step. Activate the workflow and use the generated form
WTrack buyer query citation sources with GPT-4o and Google Sheets
Quick overview This workflow tracks which sources ChatGPT cites for buyer queries.vIt runs weekly to test buyer queries against OpenAI’s GPT-4o web search, extracts the cited URLs, and logs per-query citation counts and domain classifications to Google Sheets. How it works Runs every week on a schedule trigger. Reads a list of buyer queries (including brand and competitor context) from the queries tab in Google Sheets. Sends each query to OpenAI’s gpt-4o-mini-search-preview three times with web search enabled and extracts the url_citation annotations from each response. Aggregates citations per query and domain, calculating citation totals and a sample hit rate across the three runs. Sends the unique cited domains to OpenAI’s gpt-4o-mini to classify each domain into a source taxonomy (brand site, competitor site, review platform, community, publisher, or docs/other). Appends the aggregated rows with the domain classification and an example URL to the citations tab in Google Sheets. Setup Add an OpenAI API key as an HTTP Header Auth credential (Authorization: Bearer YOUR_KEY) for both OpenAI HTTP requests. Add a Google Sheets credential with access to the target spreadsheet.
