Hire the Best Excel Experts
in Argentina

I'm passionate about Microsoft Excel (weird, right?) and I've now been Expert-Vetted by Upwork, meaning I'm in the top 1% among freelancers working with Spreadsheets. I love simplifying processes, untangling complicated formulas, automating processes with macros and creating solutions that reduce manual effort. I have broad experience working with data and looking for innovative solutions.

Do you need to optimize your tasks in Excel and Google Sheets? With experience in data entry and automation, I can help you improve your processes efficiently. ✔Data Entry: Fast and accurate in Excel, Google Sheets, and other platforms. ✔Automation: Use of Macros and Visual Basic to automate repetitive tasks. ✔Data Cleaning and Analysis: Advanced data handling with functions like Pivot Tables, VLOOKUP, INDEX/MATCH, and more. ✔PDF Conversion: Transforming PDF to Excel or Word while preserving the original format. ✔Dashboards and Reports: Creating dynamic and visually impactful dashboards. ✔Google Sheets: Automating reports and customizing spreadsheets. If you’re looking for effective solutions for your data needs, let’s talk! Carlos A. G.

What can I do for you? -Automated Reports: Stop wasting time manually creating reports. Using automated reports, you can focus on other important tasks in your business trusting that you will receive all the important information in an easy-to-read manner, without mistakes or human errors. -Interactive Dashboards: Don’t waste time consolidating data to get key information for your business. You can have a single point of view of your business’s key information. Dashboards provide customers the ability to see data all-in-one, organized and summarized in the best way. information. If the dashboard is also interactive, allows users to filter, simulate, and go deeper into the information. -Data management: Don't worry about loss and organization of your important data This service is aimed to collect, organize, protect, store, and share information about customers’ business in an appropriate way. Is key to consider these concepts of data management to avoid data loss or wrong registration. At the end of the day, that means wasting time and/or money. -Data Entry forms: Ensure easy, firefly, and free error data entry. Data forms are used to optimize the time and manner to load any transaction in a spreadsheet. In a basic way if users need to load transactions related to their business, let’s suppose purchases, they need to create a list of rows and load them one under the other. This way has many risks. Just some of these are consistency, ensuring they aren’t empty rows in the middle if they need to use reports, pivot tables etc. Using entry form, consistency of the data can be controlled, adding or deleting transactions to the list is automatic so the integrity of the list is ensured. These are just some of the benefits to use entry forms when users need to register transactions. -Data Transformation: Stop wasting time manually transforming data. You can get these data transformed into a spreadsheet as requested. Saving time and avoiding transformation manual errors. It can be done for a one-time task or for a repetitive task (Ex: Transforming credit card statements every month). -VBA Code & Advanced Functions: Don’t limit your requirements! Sometimes some desired functionality is not feasible using the basic functions of excel. Many times, a combination of functions or function + VBA code is necessary to achieve the perfect solution. VBA code can provide more tools to get the desired solution. VBA extends, the already extensive, resources that Excel has to achieve solutions. Way of working My first task is to listen to customers. I’m pretty sure the way to come up with the best solution is to understand the needs of the customer and the context of their business. Professionals looking for help on a project want someone who understands the need very well and who is realistic about the proposal Alter that, we are going to work together on the design of the project. Once we agree…. Let’s start building the solution! Before completing the project, we can check if the solution solves customer needs… After the project is complete. We can keep in contact in case you need any minor updates or new projects. Of course, you can also make a questions During the contract, feel free to suggest any adjustments such as adding specific colors or a company logo. Finally, let me emphasize the importance of communication for me. We need to take time to be sure the project complete customer expectations before closing it. Feel free to ask me any questions regarding my experience, I have more than 15 years working in excel, and how I can help. Below are some examples of projects in my portfolio. Don't hesitate to contact me with any doubts or questions! Leonardo

Most operations problems aren't tech problems. They're decision problems with tech symptoms. I'm Milton. I spent 15 years inside fast-growing operations in LatAm — most recently as COO of a fintech scaling from 20 to 60 people, and before that across consulting, recruiting, and clinical trial operations. Today I work independently with a small number of clients on the kind of problems that fall between the CEO's strategy and the team's day-to-day execution. My past clients include MercadoLibre, Block, and KPMG, where I worked on operational and digital transformation projects across LatAm. THE PATTERN I USUALLY SOLVE Revenue keeps climbing, but data lives in 8 places, processes break weekly, and the team is one resignation away from chaos. You don't need another deck. You need someone who diagnoses the real bottleneck, prioritizes ruthlessly, and builds the fix — fast. HOW I WORK Diagnosis in 2 weeks, not 2 months. Then I design and build the fix — usually a combination of process redesign, automation layer (Apps Script, Power Automate, Python, AI agents), and dashboards your team will actually use. I leave you with a system that runs without me. RECENT WORK - Built a recruitment forecasting and campaign tracking system for a clinical trials operator across 6 LatAm countries — replaced 3 disconnected spreadsheets and reduced weekly reporting from 5 days to 4 hours. - Designed and deployed a variable compensation framework for a 40-person operations team across LatAm — modeled in Excel, deployed via Google Sheets dashboards, adopted by senior leadership in 3 weeks. - Implemented a CRM migration and document infrastructure overhaul for an investment fund — DealCloud setup, Microsoft 365 + Teams + SharePoint provisioning, 67GB historical data migration, completed in 6 weeks. MY STACK Google Workspace: Apps Script, Sheets, Docs, Drive, Looker Studio Microsoft 365: Excel, Power Automate, SharePoint, Teams, Graph API, Power BI Automation & AI: Python, n8n, Claude API, GPT API, AI agent orchestration CRM & Ops: DealCloud, Notion, Airtable, Monday Data: BigQuery, SQL HOW ENGAGEMENTS WORK I take 2–3 clients at a time, on monthly retainer (USD 6–12k/month) or scoped fixed-fee projects (USD 8–30k). I don't do hourly work below USD 3k or one-off scripts — there are great freelancers for that, and I'm not one of them. Best fit: founder or operations lead of a scale-up (USD 3–30M revenue) who needs senior operational thinking + execution capacity, without committing to a full-time hire. Not a fit: quick formulas, single-script jobs, or projects without a real operational owner on your side. First call is 30 minutes, free. We figure out if it's a fit. If not, I'll point you to someone who is.
