Online JSON Viewer
View large JSON files online with Gigasheet, including healthcare price transparency machine-readable files (MRFs). No desktop software, database setup, or local parser required.
- Built for large JSON: Upload .json files and Gigasheet parses, flattens, and opens the contents in a spreadsheet-style browser view.
- Useful for MRF analysis: Search, filter, sort, group, and inspect negotiated-rate data without trying to open massive JSON files in a text editor.
- Cloud-scale file support: Work with very large JSON files, including price transparency files that are too big for typical desktop tools.

How to View Large JSON and MRF Files Online
- Sign up for a Gigasheet account.
- Upload your .json file. For large healthcare price transparency MRFs, you can upload zipped JSON files or grouped files to save time.
- Gigasheet processes, parses, and flattens the JSON into a table you can open in your browser. Large files may take several minutes to process.
- Use filters, search, groups, and exports to inspect the fields that matter, such as payer, provider, billing code, negotiated rate, plan, geography, or file metadata.
If the JSON you are opening is a payer Transparency in Coverage file, go straight to MRF Viewer. It is the same engine tuned for that one job: it flattens to the rate level rather than the top level, so the negotiated rate lands in its own column instead of collapsing into unusable text.
Working with healthcare price transparency data at scale? Gigasheet turns raw MRF JSON into analysis-ready rate intelligence, and the Price Transparency API puts benchmarks and scores directly in your own systems.
- Create an account, then upload your JSON file from your computer or connect cloud storage such as Google Drive, AWS S3, OneDrive, or Dropbox. If you have multiple JSON files, zip and upload them together.
- Gigasheet decompresses, parses, and flattens the JSON so nested records can be viewed as rows and columns. This is especially useful for machine-readable files that are difficult to inspect in a browser, text editor, or spreadsheet.
- Once processing is complete, open the file from your Library to review the extracted row and column structure. For price transparency work, this makes it easier to inspect negotiated rates, payer and plan details, provider fields, billing codes, and other MRF attributes.
- Use filters, search, groups, and cleanup tools to narrow large JSON files to the records that matter. Healthcare teams can use this workflow to validate MRF contents, investigate outliers, prepare benchmark cuts, or export focused slices for downstream analysis.
- To convert JSON to CSV, open the table and use File > Export. Gigasheet creates a downloadable CSV export so the parsed data can move into reporting, modeling, or internal workflows.
Gigasheet is a practical online JSON viewer for large files and a healthcare price transparency platform for teams that need MRF data to become usable market intelligence.
Drive Growth with Market Intelligence
MRF JSON Exploration
Open large machine-readable JSON files in a browser-based table. Inspect payer, provider, code, plan, and negotiated-rate fields without local infrastructure, or use MRF Viewer for price transparency files specifically.
Search, Filter & Export
Filter massive JSON files to the records that matter, group data for analysis, remove noise, and export focused CSV slices for pricing, reimbursement, or market intelligence workflows.
Security for Sensitive Workflows
Gigasheet uses encryption in transit and at rest, follows industry safeguards including SOC 2, and does not sell the data you load into the platform.
