Cloud spreadsheet: formulas, ARRAYFORMULA, QUERY, Apps Script, BigQuery, pivot tables.
Before starting, we run a 1-minute tech check — microphone, ambient noise, connection. If your setup isn't good enough, the test is fully refunded.
Stop listing 'Google Sheets' as a skill and start proving it — a 15-minute AI oral exam tests your ARRAYFORMULA, QUERY, Apps Script and data stack knowledge, then scores you from 0 to 100.
The Plume Google Sheets badge certifies your ability to use Google's cloud spreadsheet at a level that actually moves the needle on real projects. In 15 minutes, an AI examiner walks you through your own work: the architecture of your files, how you combine ARRAYFORMULA, QUERY and LAMBDA/MAP, what Apps Script automations you've built, how you handle performance on large datasets, and how Sheets fits into a broader data stack alongside BigQuery, Looker Studio or AppSheet. The oral also probes your judgment — specifically, when Sheets is the right tool and when you'd push a team toward something else.
A self-declared 'Google Sheets' skill on LinkedIn is invisible noise. This badge cuts through that by producing a 0-to-100 score, a proficiency level (Novice, Proficient, Advanced, Expert) and a detailed evaluation report. Claude Opus reads the full transcript and scores five weighted dimensions: technical depth, real-world problem solving, ecosystem integration, tool judgment and communication clarity. There's no multiple-choice shortcut — just your spoken answers, your real examples and your live reasoning.
This badge is built for data analysts who live in Sheets, ops managers who automate workflows, freelancers who deliver Sheets-based tools to clients, and anyone who has built real expertise but lacks a credible signal to show for it. Whether you're job hunting, pitching a contract or asking for a salary bump, the shareable badge URL gives whoever's reading your profile something concrete to click on.
Here are the concrete dimensions the AI examines during the 15-minute oral.
Mastery of ARRAYFORMULA, LAMBDA, MAP, REDUCE and BYROW to build dynamic, self-expanding ranges without dragging formulas across thousands of rows or relying on manual updates.
Using the QUERY function with SELECT, WHERE, GROUP BY, ORDER BY and PIVOT clauses to filter, aggregate and reshape data directly inside the spreadsheet, without exporting to a proper database.
Writing Apps Script to build time-based triggers, custom menus, REST API integrations and automated workflows that go beyond what native formulas can handle — including error handling and logging.
Building performant pivot tables and using Sheets' structured Tables feature to enforce data consistency, simplify formula references and make files easier to hand off to teammates.
Connecting Sheets to BigQuery via the native connector, feeding Looker Studio dashboards, syncing with AppSheet and orchestrating data flows through Zapier or Make for lightweight hybrid pipelines.
Designing readable, maintainable dashboards: granular access permissions, scheduled data refreshes, advanced conditional formatting and performance tuning when files grow into hundreds of thousands of rows.
Knowing when Sheets is no longer the right call — volume constraints, latency, governance — and being able to argue a migration to Airtable, BigQuery, a relational database or Notion with clear, objective criteria.
Practical knowledge of what's actually changed with smart chips, Gemini in Sheets, structured Tables and newer functions like LAMBDA — not just awareness that they exist, but how they've shifted your day-to-day workflow.
Final scoring is performed by Claude (Anthropic), which reads back the full transcript and applies this weighted criteria grid.
The candidate demonstrates hands-on command of advanced features — ARRAYFORMULA, QUERY, LAMBDA, Apps Script — through specific, project-rooted examples rather than textbook definitions or vague claims.
Ability to walk through concrete situations — a slow file, out-of-sync data, broken access controls — and explain the solution with a clear, structured line of reasoning that shows how they actually think under pressure.
Understanding of BigQuery, Looker Studio, AppSheet and Zapier/Make connectors, with the ability to describe a coherent data pipeline where Sheets plays a specific, well-reasoned role.
The candidate can identify where Sheets hits its ceiling and justify alternative choices with objective criteria: data volume, query latency, collaboration needs, governance requirements or cost.
Explanations are precise, well-structured and free of unnecessary jargon. The candidate calibrates their level of detail to the question and consistently anchors abstract points in concrete examples.
A Plume session takes about 20 minutes, from tech check to badge delivery.
The AI confirms your microphone is working and the audio connection is stable. No screen sharing required — the entire exam is spoken. You can have notes nearby, but the examiner expects spontaneous, experience-based answers, not readings.
You introduce yourself briefly and walk the examiner through the most complex Google Sheets project you've built: data volume, the formulas or scripts at its core, who used it and what business problem it solved.
The AI digs into the calibrated themes: ARRAYFORMULA/QUERY/LAMBDA combinations, Apps Script you've written, dashboards you've delivered, BigQuery or Looker Studio integrations you've set up, and migration calls you've made. Questions adapt in real time to your answers.
The examiner asks what recent Sheets changes — structured Tables, Gemini, new functions — have actually shifted in your practice, and in which scenarios you'd recommend a different tool entirely.
Claude Opus analyzes the transcript and generates a 0-to-100 score with your proficiency level (Novice, Proficient, Advanced, Expert), a per-criterion evaluation report and a shareable badge URL ready to drop into your LinkedIn profile.
Your score out of 100 translates into a level a recruiter can grasp at a glance.
You use Google Sheets for straightforward tasks: data entry, basic SUM/IF/VLOOKUP formulas, manual formatting. You mostly work inside files others have set up and haven't yet explored ARRAYFORMULA, QUERY or Apps Script.
You build Sheets files from scratch, combine ARRAYFORMULA with common formulas, create pivot tables and use QUERY to filter data. You understand sharing permissions and range protection, and you've dabbled in Apps Script even if it's not a regular tool.
You design maintainable operational dashboards, you're fluent with LAMBDA/MAP/REDUCE, you write Apps Script with triggers and custom menus, and you connect Sheets to external sources like BigQuery, REST APIs or Zapier. You tune performance on large files and advise teammates on architecture.
Sheets is a first-class component of your data stack. You make deliberate trade-offs between Sheets and alternatives like Airtable, BigQuery or a relational database, deploy complex solutions mixing Apps Script, BigQuery connectors and Looker Studio, and are the go-to person in your org for spreadsheet architecture decisions.
No degree or years of experience required to take the badge. Here are the profiles it makes the most sense for.
You build reports and dashboards in Sheets every day and want your actual skill level — QUERY, ARRAYFORMULA, BigQuery connector — to be visible and credible on your profile, not just a line item on a resume.
You automate business processes with Sheets and Apps Script and want to turn that cross-functional skill into something concrete that hiring managers and leadership can actually evaluate.
You deliver Sheets-based tools to clients and want an objective proof point to include in proposals or on your website that justifies your rates without requiring a lengthy portfolio review.
You've built real Sheets expertise through coursework or internships and need a credible signal to offset the lack of long professional track record when applying to analyst or ops roles.
You want to objectively benchmark candidates' or team members' Sheets level before a data project or a hire, without running ad hoc tests disconnected from real-world usage.
Where and how your Google Sheets badge will help you day to day.
You're applying for an ops analyst role that lists 'advanced Google Sheets proficiency' as a requirement. Your Advanced badge with a score of 78/100 and the detailed report do the validation work so the recruiter doesn't need to test you manually during the interview.
You're quoting a project to build a production tracking tool in Sheets. You attach your Expert badge URL to show the client you know Apps Script and the BigQuery connector — they sign without asking for additional references.
A Head of Data asks 12 analysts to take the badge to map their real levels before deciding who will upskill the team on LAMBDA functions and structured Tables for an upcoming migration project.
You come from marketing and taught yourself Sheets to build campaign dashboards. The badge certifies that level without a Google certification or a CS degree, and helps you make the case for a transition into a data or ops analyst role.
You add the badge URL directly to your LinkedIn certifications section. Recruiters can click through to see your score, your level and the evaluation report — not just a logo or a self-declared skill tag.
During a performance review, you present your Expert Google Sheets badge to argue for ownership of more complex data projects and the compensation bump that should come with them.
A few minutes to check you have everything you need.
At the end of your session you don't just get a score — here's everything that awaits you.
You get a precise 0-to-100 score and an official proficiency level (Novice, Proficient, Advanced, Expert) that reflects your actual command of Google Sheets — formulas, Apps Script, integrations and all.
A full written report breaks down your strengths and growth areas across all five scoring dimensions: technical depth, problem solving, integration fluency, tool judgment and communication clarity.
Your exam audio is stored securely and stays private by default. You control whether to share it — it serves as evidence if you ever need to verify or contest your result.
You get a dated public URL you can paste into your LinkedIn profile, resume, client proposal or job application email. Anyone can verify your level and score in one click, no login required.
