Gigasheet

What is Gigasheet?

Gigasheet is a browser-based big data spreadsheet that handles files far beyond the row limits of desktop spreadsheet apps. You upload CSV, TSV or Excel files, or connect a data warehouse, and then filter, group, merge and enrich the data in a familiar grid without writing SQL.

The company has shifted much of its focus to healthcare price transparency. Its homepage now leads with an analytics platform built on more than 150 billion payer rates and 3.4 million scored providers, aimed at hospitals, insurers, employers and MedTech firms. The general Premium Individual spreadsheet plan remains on sale, and Gigasheet says it welcomed over 150,000 users in 2024. It also reports SOC 2 Type 2 certification.

Key Features

• Big data grid: Gigasheet opens CSV and tabular files with millions of rows in a browser spreadsheet. Directory listings cite capacity of up to one billion rows, while Premium Individual covers 25 to 75 million rows and 25 to 75 GB of storage.
• No-code analysis: Gigasheet provides filtering, grouping, pivots, find and replace and calculations through point-and-click menus. Analysts can slice large exports without SQL, Python or help from a database administrator.
• Sheet Assistant: Sheet Assistant answers questions and performs actions on your data from plain-language requests. It helps you explore big tables quickly without writing a query for every step of the analysis.
• AI Formula Writer: The AI Formula Writer turns a written description into a working formula for custom calculations. Gigasheet launched it in 2024 for users who know the result they need but not the syntax.
• Bulk file combining: Gigasheet merges many files at once by matching column names rather than requiring identical layouts. That saves time when monthly exports drift slightly in structure or column order.
• Live warehouse queries: Gigasheet connects live to Snowflake, Databricks and other data stores through its spreadsheet interface. Cleaned or enriched results can be written back to the warehouse in a governed way.
• Data enrichment: A RevenueBase partnership adds up to 25 business and contact columns to sales lists. Healthcare users can enrich files with NPI and CMS reimbursement data for provider analysis.
• Healthcare AI Agent: The healthcare AI Agent turns a plain-language question into an interactive intelligence report with the backing data. It draws on Gigasheet’s database of more than 150 billion payer rates.
• Collaboration and API: Shared workspaces, inline comments and saved views let teams work on the same sheets. An enterprise API and Zapier integration automate imports, exports and repeated actions.

Pros

• Handles huge files: Gigasheet opens files that would overwhelm a desktop spreadsheet. Capterra reviewers mention processing a billion rows and highlight how much faster it feels than Excel on large datasets.
• Familiar interface: The spreadsheet layout feels familiar to anyone who already uses Excel. Non-technical staff can filter, group and pivot large exports without learning SQL or setting up a database.
• Well rated support: Gigasheet earns strong user scores for help and value. Capterra lists 4.9 out of 5 from seven reviews, with customer support rated 4.7 and value for money 4.8.
• Free starting point: The free online CSV viewer lets you open and filter large files in a browser after signing up. You can test speed on your own data before paying for Premium.
• Warehouse access without SQL: Live connections to Snowflake and Databricks put warehouse tables in front of business users. Write-back means cleaned results return to the source rather than living in stray CSV files.
• Security credentials: Gigasheet reports SOC 2 Type 2 certification for its platform. Directories add that data is encrypted at rest and in transit, which helps when you upload customer or patient files.

Cons

• Unclear pricing: Gigasheet does not publish Premium prices on its pricing page. Directories report figures from $14 to $95 per month, so you only see the real cost at checkout or on a sales call.
• Healthcare focus: The website now centres on healthcare price transparency rather than general spreadsheets. Users outside healthcare may find less documentation and roadmap attention aimed at their use cases.
• No JSON on Premium: Premium Individual does not support JSON files, according to the official pricing page. Teams with nested JSON exports must convert them first or speak to sales about other plans.
• Limited advanced analytics: Gigasheet is not built for machine learning, statistical modelling or complex macros. Directory reviews note the gap, so heavy modelling still needs Python, R or a dedicated BI tool.
• Internet required: Gigasheet runs entirely in the cloud, so you need a connection to work on any sheet. Processing speed can also vary with platform load, according to one directory review.
• Missing comforts: Capterra reviewers have asked for dark mode, JSON export and better beginner guidance on advanced features. New users may need extra time to find the more powerful functions.

Who is Using Gigasheet?

• Data analysts: Analysts exploring large CSV exports and reports.
• Sales and marketing teams: Teams cleaning and enriching lead lists.
• Healthcare organisations: Payers, providers and employers comparing negotiated rates.
• Security teams: Analysts reviewing very large log files.

Pricing

Gigasheet uses a freemium model, but its pricing page lists plans without public prices (official pricing page, checked October 2026).

Directories disagree: Capterra lists $95 per month, FitGap reports $25 per month on annual billing plus a Business plan from $4,950 a year, and Cybernews cites a Pro plan from $14. Treat these numbers as indicative and confirm the final figure at checkout before committing.

What Makes Gigasheet Unique?

Gigasheet pairs a spreadsheet grid with a cloud database engine, so business users can work on billion-row files with the same filters and pivots they know from Excel. Its second differentiator is data: a healthcare price transparency library of more than 150 billion payer rates turns the product into a market intelligence service, not just a file viewer. Few spreadsheet tools combine warehouse write-back, enrichment and a sector-specific dataset in one place.

Compatibilities and Integrations

• Files: CSV, TSV and Excel uploads, with JSON handled by the MRF Viewer.
• Data warehouses: Live queries and write-back for Snowflake and Databricks.
• Automation: Enterprise API, Analytics API and Zapier workflows.
• Apps: Capterra lists over 50 native integrations, including HubSpot and Asana.

How We Rated It

Summary

Gigasheet suits analysts, sales teams and healthcare organisations who need to work with files too large for Excel but lack database skills. Its main limitation is opaque pricing, and the company’s growing healthcare focus may matter to general users. Advanced modelling still needs other tools. Test the free CSV viewer with your largest real export before you buy Premium.
