Cloud spreadsheet for CSV and tabular files with tens of millions of rows, from a company that now also sells healthcare price data.

Gigasheet is a browser spreadsheet for CSV and tabular files too big for Excel, handling up to 25 million rows per sheet on Premium. The company now leads with healthcare price-transparency data, which is sold on quote. Premium starts at $95 a month billed monthly, and a free account is available with small storage.

The bottom line

Good for giant flat files; check the free limits and the JSON gap first.

What it is, and why we rate it

One line each. Open a row for detail.

What it really isA browser spreadsheet for very large CSV files, from a company now focused on healthcare price data.
Our takeIf a CSV export crashes Excel and you only need to filter, group and export, Gigasheet gets you there without SQL.
Pay monthly for a one-off job, since $95 is easier to swallow than a year. If your work is ongoing, compare it with a proper database first, and note that JSON is outside the self-serve plan.
Why we rate itHandles up to 25 million rows per sheet with merge, filter and export tools, and prices for the self-serve plan are public.
The catchThe company's focus has moved to healthcare data, free-tier limits are undocumented on the pricing page, and Premium Individual rejects JSON.

Is Gigasheet free?

Gigasheet's tool pages let you create a free account. The pricing page does not list a free plan, and the latest support article we found, from April 2024, gives the free Community tier 1 GB of storage. Check the limits inside the app before relying on it.

How many rows can Gigasheet handle?

Premium allows up to 25 million rows per sheet, and the pricing page describes Premium Individual as handling 25 to 75 million rows with 25 to 75 GB of storage. Larger files and quotas fall under Enterprise.

What file types does Gigasheet open?

Gigasheet lists XLS, XLSX, CSV, TSV, PCAP, TXT, Numbers and LOG files, and it unzips zip files automatically. JSON is not supported on Premium Individual; the MRF Viewer, sold separately, handles large JSON price files.

Is Gigasheet a healthcare company now?

Its homepage leads with healthcare price-transparency data, rate scores and an analytics API, sold through demos. The self-serve big-data spreadsheet is still sold online as Premium.
