How to Escape the Excel Hell?
If you're a product manager at a 50-person fintech startup, there's a good chance you've inherited at least one "mission-critical" Excel file that nobody fully understands anymore. You know the one: it was built years ago by someone who's since left, it has 14 tabs, 3 conditional formatting rules that conflict with each other, and it lives in a shared Google Drive folder called "FINAL_v2_USE_THIS_ONE."
This is the Excel hell we're talking about, and it's costing you more than you think!
Spreadsheets were never meant to be the operational backbone of a scaling company. They were designed as calculation tools that were never intended to handle real-time data flows, cross-team collaboration, audit trails, or the kind of compliance requirements that fintech companies face daily. Yet here we are.
This article walks you through exactly how to get out. Not just "use better tools", but a real, phased migration plan that won't disrupt your team mid-sprint.
What we will cover:
Before jumping into solutions, it's worth naming what's actually at stake. For fintech PMs, spreadsheet dependency isn't just an efficiency problem, but a risk management problem.
Data integrity breaks at scale: When five people are updating the same file, version conflicts are inevitable. One wrong cell reference, one misaligned paste, and your KYC tracking or revenue reconciliation is off. In a regulated environment, that's annoying for sure, but it's also a potential compliance issue.
Spreadsheets don't have proper access controls: Sharing a file is all-or-nothing in most setups. You can't give your operations analyst read access to one section while protecting sensitive financial data in another without elaborate workarounds that inevitably break.
Manual data workflows kill velocity: Every hour your team spends copying data between spreadsheets, running manual exports, or debugging a broken macro is an hour not spent building product.
There's no audit trail: Who changed that risk threshold value on Tuesday? In Excel, good luck figuring that out! In a regulated fintech environment, that absence of auditability is a liability.
You can't fix what you haven't measured. The first step is running an honest audit of every spreadsheet your team actually relies on for operational decisions.
Go through your shared drives, Slack channels, and email threads and catalog each file. For each one, answer:
You'll almost certainly discover two categories: spreadsheets that are "critical" because they're embedded in daily workflows, and spreadsheets that exist because someone built them once and nobody questioned whether they were still needed.
The second category you can simply retire. The first category is your migration priority list.
Not every spreadsheet should be replaced with the same type of tool. The fix for a reporting dashboard is different from the fix for a manual data entry workflow.
Broadly, spreadsheets in fintech teams tend to fall into a few buckets:
Reporting and analytics: Dashboards, KPI trackers, cohort analyses. These should move to a proper BI tool. Metabase, Redash, or Looker (depending on your stack and budget) are the natural home for this work. Once a metric lives in a connected dashboard, it updates automatically and everyone sees the same number.
Operational workflows: Things like onboarding checklists, customer escalation tracking, or loan review queues. These belong in an internal tool or lightweight database like Blitz, Airtable, Notion, or a custom internal tool built with something like Retool or a no-code platform.
Data transformation and one-off analysis: The ad hoc work where someone pulls a CSV, cleans it, and runs some numbers. This is the hardest to fully replace, and honestly, it might not need to be. The goal isn't zero spreadsheets, it's no spreadsheets as the source of truth for anything operational.
Integration middleware: Spreadsheets being used as the "glue" between two systems that don't talk to each other. This is where the technical debt is highest and where proper automation pays off fastest.
The reason so many spreadsheet migrations fail is that teams try to replace the spreadsheet without fixing the underlying data problem. If the reason you have an Excel file is that you don't have a reliable source of truth for a dataset, replacing it with Airtable doesn't actually solve anything. You've just moved the problem.
Before migrating any workflow, ask: where should this data actually live?
For most fintech startups, that means investing in a proper data warehouse (Snowflake, BigQuery, or even just a well-structured Postgres database) with a clean ETL layer. Yes, this has upfront cost. But it's the foundation that makes everything downstream work properly: your BI tools, your automation, your compliance reporting.
If you're not at the stage where a full data warehouse makes sense, at minimum centralize your core entities (users, transactions, products) in a database rather than in files. A shared database with read access for your tools is already a massive improvement over a shared spreadsheet.
A large portion of spreadsheet hell isn't the spreadsheet itself. It's the manual process wrapped around it. Someone exports a CSV every Monday morning. Someone else copies rows from one sheet to another. A third person formats and sends a report to the finance team.
These workflows are where automation tools shine. Zapier and Make can handle simple trigger-based flows. For more complex, conditional logic (the kind that shows up in fintech operations) a proper workflow automation tool or a custom internal tool gives you more control.
The goal here is to eliminate human steps in data movement. Every time a person touches data to move it from one place to another, you've introduced an error vector. Automation removes that vector and also makes the process auditable. You can see exactly what ran, when, and what it produced.
This is the step most teams skip because it feels expensive.
For the spreadsheets that are functioning as lightweight applications (a customer review queue, a fraud flagging tracker, a manual reconciliation flow) what you actually need is a simple internal tool. A form that writes to a database. A table view with filters and status fields. A button that triggers an action.
No-code and low-code platforms have made this dramatically more accessible. You don't need an engineering sprint to build a basic CRUD interface for your ops team anymore. Tools like Retool, Internal, or no-code builders allow PMs or analysts to build functional internal tools without writing backend code.
The key differentiator compared to a spreadsheet: the data lives in a real database, there's proper access control, there's an audit log, and you can connect it to your other systems via API rather than CSV exports.
For fintech teams specifically, this shift also makes compliance conversations easier. When an auditor asks how you track a particular process, "here's a database-backed tool with a full event log" is a much cleaner answer than "here's a spreadsheet in Google Drive."
The biggest mistake in any spreadsheet migration is trying to flip everything at once. You'll disrupt workflows, lose institutional knowledge embedded in those files, and burn political capital with the team.
Instead, migrate in priority order: start with the highest-risk spreadsheets (the ones where errors have real consequences) and the ones with the highest operational cost (the ones that eat the most manual time every week).
Run parallel systems during transition. Keep the spreadsheet alive while the new tool is validated. Only retire the spreadsheet once the team has confirmed the new system is reliable and complete.
Document what the spreadsheet was doing before you shut it down. That documentation becomes your test plan for the replacement.
Tools matter, but culture matters more. Even after a successful migration, spreadsheets will creep back if the default behavior is "I need to track something, let me open Excel."
The shift to make is this: spreadsheets are for exploratory analysis, not for running operations. If something needs to happen reliably, repeatedly, and with accountability, it needs to live in a proper tool with proper infrastructure.
As a PM, you're well-positioned to model this behavior. When a team member suggests a new spreadsheet-based process, push back constructively: "What database should this actually live in? What's the right tool for this workflow?" Over time, that question becomes instinct.
Teams that successfully move off spreadsheet-driven operations consistently report the same benefits: fewer errors surfacing in prod or in compliance reviews, faster onboarding for new team members, and significantly less time spent on data wrangling each week.
For a fintech PM, the less obvious benefit is credibility. When your data is clean, your dashboards are live, and your operational workflows are auditable, every conversation with investors, auditors, or your engineering team gets easier. You're not defending numbers from a file anymore, you're pointing to a system.
Conclusion
Getting out of Excel hell isn't a one-day project, but it's also not the multi-year initiative it used to be. The tools available today (BI platforms, workflow automation, no-code internal tool builders) have made this migration accessible to teams that don't have a dedicated data engineering function.
The path forward:
The fintech startups that scale well are the ones that treat data infrastructure as a product decision, not just an engineering concern. As a PM, that's your domain. Start there.
