Computer Use
You're Manually Updating Spreadsheets While Your Competitors Already Automated Theirs
Stop wasting 3+ hours a week on spreadsheets. Coasty's computer use AI agent reads, fills, and processes any sheet automatically. Try it free.
The average office worker spends 3 hours every single week just working in spreadsheets. That's 150 hours a year per person. For a team of 10, you're burning 1,500 hours annually on copy-pasting, reformatting, and praying nobody introduced a typo. And here's the brutal part: research from the University of Hawaii found that 88% of spreadsheets contain at least one error. Not occasionally. Routinely. JP Morgan found this out the hard way when a single Excel formula mistake, dividing instead of averaging two interest rates, contributed to a $6.2 billion trading loss in 2012. That wasn't bad luck. That was the inevitable outcome of trusting humans to do repetitive, high-stakes data work at scale. Over 40% of workers spend at least a quarter of their entire work week on manual, repetitive tasks like data collection and entry, according to Smartsheet's workforce research. You already know this is a problem. The question is why you're still doing it manually.
How Coasty's Computer Use Agent Handles This
Coasty is a computer use agent, meaning it literally sees your screen and operates your software the same way a human would, except it doesn't get tired, doesn't fat-finger cells, and doesn't take a 20-minute break after 45 minutes of data entry. You point Coasty at a task, whether that's pulling figures from PDFs into a master sheet, cross-referencing two workbooks and flagging discrepancies, filling out web forms from spreadsheet rows, or reformatting exported data into a standardized template, and it just does it. No macros to maintain. No VBA scripts that break when someone upgrades Office. No RPA bots that fall apart the moment a UI changes by two pixels. Coasty scored 82% on OSWorld, the industry-standard benchmark for computer use agents. That's not a marketing number. That's a reproducible score on real-world computer tasks that other agents consistently fail. It handles Excel, Google Sheets, CSV workflows, and any web-based spreadsheet tool without needing an API or a developer to wire things together. The computer use approach means if you can show a human how to do it once, Coasty can do it at scale.
Why This Beats Everything Else
- ●No brittle macros or VBA: Traditional Excel automation breaks the moment someone renames a tab or moves a column. Coasty reads context visually, the same way a person does, so minor layout changes don't kill your workflow.
- ●No API required: Most automation tools need a developer to build integrations. Coasty works at the screen level, so it connects your spreadsheet to any other tool, web app, or database without a single line of code.
- ●Error rates near zero vs. the 5-6% human baseline: Studies put manual spreadsheet data entry error rates at around 5% per cell. At scale, that's catastrophic. A computer use agent applying consistent logic doesn't drift, rush, or misread a number after hour three.
- ●Handles the weird stuff: Real spreadsheet work is messy. Merged cells, inconsistent formatting, multi-tab lookups, conditional logic. Coasty navigates actual software interfaces, so it handles the edge cases that rule-based RPA tools simply refuse to touch.
88% of business-critical spreadsheets contain errors. Coasty's computer use agent brings that number to near zero, because it applies the same logic every single time, on every single row, without exceptions.
Real Results
When teams replace manual spreadsheet work with a computer use agent like Coasty, the math changes fast. A finance analyst spending 3 hours a week on spreadsheet reconciliation gets that time back entirely. A sales ops team that manually copies CRM exports into reporting templates every Monday morning, a process that typically takes 2 to 4 hours, runs it in minutes. An operations team cross-checking inventory data across three different exported CSVs, a task riddled with the kind of human error that quietly corrupts decisions for weeks before anyone notices, gets clean, verified output automatically. Auditors at Big 4 firms currently spend 5 to 10 hours per week manually processing client spreadsheet files. A computer use agent cuts that to near zero. The compounding effect is real: fewer errors means fewer correction cycles, fewer correction cycles means faster closes, and faster closes means decisions get made on accurate data instead of last week's best guess.
Spreadsheet work isn't going away. But manually doing it is now optional. Coasty's computer use AI agent handles your sheets the same way a meticulous human analyst would, just faster, at any hour, and without the 88% error rate that comes standard with manual processes.
