SheetPair is a browser-based tool for comparing two CSV or Excel files. Upload both files, map the columns you want to match on, and instantly see what's matched, what's different, and what's missing.
How it works: Drop in two files, select your key columns, and SheetPair shows matched rows, rows with differences (highlighted cell by cell), and rows that only exist in one file. Results are ready in seconds, even with thousands of rows.
Privacy-first: All processing runs in your browser using Web Workers. Your files never leave your machine — there's no upload endpoint and no server-side storage. Verify it yourself in DevTools.
Smart matching: Exact matching via hash-map lookup, Jaro-Winkler fuzzy matching for typos and formatting differences (e.g., "Jon Smith" vs "John Smith"), and numeric tolerance matching for rounding (e.g., $100.00 vs $99.99).
Built for: Accountants doing bank reconciliation, analysts comparing datasets, small businesses matching vendor lists or invoices, developers validating data migrations, and anyone tired of VLOOKUP across two spreadsheets.
Free tier: Compare up to 1,000 rows with 3 reconciliations per day. No signup required. Paid plans support up to unlimited rows with AI-powered features.

Grapple's answer
Grapple is built for small to medium-sized companies who haven't successfully implemented traditional BI software like Looker, Power BI, Tableau, or other solutions like DataRails and Domo. Traditional BI software requires a lot of technical knowledge to setup, maintain, and they often make it really difficult for less technical users to customize. This means your dashboards either 1) don't work, or 2) aren't flexible and easy to use enough to let operators adjust them as they need during the course of businesses.
Grapple is designed from the beginning for non-technical operators across marketing, sales, and finance.
SheetPair's answer:
Most file comparison tools (Beyond Compare, Diffchecker) compare lines of text. SheetPair understands rows and columns — it matches records across two files, highlights differences per field, and shows what's missing from each side. It's purpose-built for data reconciliation, not generic diffing. Plus it's free to start with no signup required.
Grapple's answer
Grapple is great for data savvy operators who love working with data. We're particularly helpful for companies with 25 to 500 employees who serve other businesses (B2B) and are focused on improving their CRM analytics and SaaS metrics. If you're using apps like Salesforce, Hubspot, Zendesk, Stripe, or Asana, Grapple is for you!
If you want to write data notebooks in python or SQL and want under-the-hood control of your data stack, Grapple is not for you. We recommend you try Omni or Hex.
SheetPair's answer:
Accountants, finance teams, data analysts, and operations managers who regularly need to compare spreadsheets — bank reconciliations, invoice matching, inventory audits, or migrating data between systems. Anyone who's tired of doing VLOOKUP across two files.
Grapple's answer
Jack, co-founder/CEO, had the idea for Grapple a couple years ago after spending almost a decade building in Tableau, Looker, Google Data Studio, Trevor.io, and the list goes on! Jack spent a lot of time collaborating with non-technical users in sales, marketing, bizops, finance on dashboards and after one particularly simple report that was still difficult to generate, he thought there must be a better way! Turns out, most data platforms require a ton of other tools and a ton of other people all of which are slow and expensive—delaying your time-to-insight. Jack had the idea to compress the data stack into a single tool, that maybe couldn't do everything, but would be the fastest, easiest way to pull the types of reports he pulled all the time over the last 10 years. Fast-forward to today, Andrew joined as co-founder/CTO and Grapple is now generally available and includes a suite of AI features to take Grapple's speed and ease of use even further. Let us know what you think!
SheetPair's answer:
I kept seeing people struggle with comparing two spreadsheets — writing complex VLOOKUP formulas, copy-pasting between files, or paying for clunky enterprise software. I built SheetPair to make it as simple as uploading two files and clicking a button. Privacy was a priority from day one — your data stays in your browser.

Grapple's answer
