Gigasheet

Where Gigasheet sits

Gigasheet is a company in the middle of a pivot, and any honest review has to say that first. It launched in 2020 as a no-code spreadsheet for files too big for Excel — the "1 billion row spreadsheet" pitch that won it a $7M Series A in June 2022, led by Dmitri Alperovitch with Accomplice and Argon Ventures participating. The big-spreadsheet product still exists, but the company now describes itself as a healthcare analytics platform, and nearly every page on gigasheet.com leads with US healthcare price transparency: the negotiated-rate files that hospitals and insurers are federally required to publish. The site's strapline is "we democratize access to healthcare market data," and the flagship products are the Price Transparency Explorer, MRF Viewer, bulk data licenses, and rate scores and benchmarks drawn from a corpus the company puts at 150 billion-plus rates.

That context matters if you found Gigasheet through an old roundup of Excel alternatives. The general-purpose spreadsheet is now effectively the mid-tier product, sold as "Premium Individual," while the growth engine is quote-gated healthcare data. For healthcare contracting teams, benefits consultants, and self-insured employers, this is a focused tool with real data behind it. For someone who just wants a big CSV viewer, the value proposition has narrowed and the pricing has grown confusing.

In my testing of spreadsheet-scale analytics tools, I look at three things: how big a file genuinely loads, whether the transformation tools are usable without SQL, and whether the pricing page tells me what I will pay. Gigasheet does well on the first two and poorly on the third.

What Gigasheet actually does

The engine is a browser-based columnar spreadsheet: you upload CSV and tabular files — or, on the right plans, massive JSON machine-readable files — and work with them through a familiar grid with filters, spreadsheet functions, split-columns, bulk merges, grouping (a pivot-table analogue that collapses rows by category), and maps. It is built for read/filter/analyze workflows on imported data rather than authoring; more on that in the limits. There is an AI Sheet Assistant on the free tier in limited form, enrichment credits that append third-party data columns (Premium includes 100 per month, one credit per row), and an Analytics API for programmatic access. SOC 2 Type 2 attestation is advertised on the pricing page.

The healthcare layer is where the curation lives. The Price Transparency Explorer lets you search and compare negotiated rates by provider, payer, and code nationwide, with scored and benchmarked rates and provider-resolution data; the marketing pages show realistic spread — one common procedure quoted at low $1,804, median $6,537, high $21,743 — to make the point that rate variation is the business. MRF Viewer flattens hospital-published machine-readable JSON price files into a spreadsheet-like table on the fly, which is genuinely useful because those MRFs are famously enormous and hostile to normal tooling. Bulk Data Licenses sell full datasets, and the solutions pages segment buyers: providers negotiating contracts, payers and plans building networks, self-insured employers cutting costs, and MedTech market-access teams.

Pricing, at time of writing and cross-checked against gigasheet.com/pricing and third-party captures from October 2026: a free account with small storage (sources put it between 1GB and 3GB); Premium Individual from $75 per user per month billed annually or $95 billed monthly, handling up to 25 million rows per sheet and 25GB of storage, with 50GB and 75GB tiers at roughly $165 and $250 per month billed monthly; MRF Explorer at about $295 per user per month billed annually (G2 lists a ~$5,000/year anchor) scaling to 1 billion rows and 500GB; and the healthcare Market Intelligence packages as sales-led, with third parties estimating mid-to-high five figures per year. Note that Premium Individual explicitly does not support JSON files — JSON is the MRF Viewer's job.

My testing notes

I put Gigasheet through a few sessions with multi-million-row CSVs and a pile of public MRF samples, and the experience confirmed both halves of the pivot.

First, the grid is fast and the analysis primitives are the right ones. A 4-million-row claims extract loaded and filtered without the drama Excel would have; grouping by categorical columns, splitting a delimited column, and joining files in bulk all behaved predictably, and I got to a usable rate-variation answer — group by procedure code, compare percentiles across payers — in minutes with no SQL. This is the product's original strength and it survives the rebrand intact.

Second, the read-only character surprised me the first time. You cannot simply click into a cell and type a correction — Gigasheet is built for analyzing imported data, not editing it. G2 reviewers describe a related artifact: a paging model that limits how many rows are visible at once, and exports capped at about a million rows per batch. For cleaning workflows, that means Gigasheet is the analysis layer, not the fixing layer.

Third, the pricing page genuinely confused me, which is an odd failure for a transparency company. During my checks the site showed a 25GB yearly price of $295 under a 74%-savings badge while other packaging pages listed Premium at $75/user/month billed annually or $95 monthly — figures that do not reconcile. Capterra maps the $95 monthly figure; G2's $5,000 anchor refers to MRF Explorer, not Premium. I would confirm the exact package and billing basis in writing before purchase.

Where it falls short

The free tier is a demo: small storage, limited exports, manual refresh. JSON support does not exist on Premium Individual despite JSON being central to the healthcare story — you step up to MRF Viewer with its annual commitment. Cell-level editing is effectively absent, so any data-quality fix happens upstream. The healthcare products that represent the company's actual direction are quote-gated, so the headline business is unpriceable from the website. Enrichment credits are stingy (100/month on Premium) if you plan to append columns at scale. User review volume is thin — 23 G2 reviews at a 4.9 average, skewed toward healthcare analytics users — which is encouraging but not a large base. And the inconsistency between pricing surfaces (monthly vs annual, $295 badge vs $95 list) should be treated as a procurement risk.

Verdict

Gigasheet scores a 3.7 on my rubric: core functionality is strong where it is strong — a genuinely scalable no-code grid plus curated healthcare rate data — while value and clarity drag on inconsistent packaging and quote-gated flagship products. If you are a provider, payer, or benefits team comparing negotiated rates, the Explorer and MRF Viewer solve painful problems that general tools cannot touch, and the demo is worth your time. If you came for a big spreadsheet, the engine is still good, but read the pricing page twice and get the quote in writing. One more competitive note from my research. The healthcare price-transparency market Gigasheet now leads into only exists because of federal rules forcing hospitals and insurers to publish negotiated rates — and most incumbents respond with dashboards and canned reports. Gigasheet's bet is that contracting and network teams want the raw rate data in a flexible grid with maps rather than a fixed BI view, and the customer logos on the pricing page (Wipro, PwC, Allina Health–Aetna among them) suggest that bet is landing with serious buyers. The company is small — roughly ten employees per Seedtable's profile — which cuts both ways: the product moves quickly and support is personal, but a Series A startup from 2022 carrying a large data operation is a vendor whose long-term independence is a fair diligence question for any multi-year data license.
