## About Data Utility

Data Utility is a set of 22 free online data tools that run entirely in the browser. You can convert files between JSON, CSV, Parquet and Excel, merge or split files, turn pasted text or an API response into a table, and edit nested JSON as a table. Other tools format and validate JSON, CSV, XML and YAML, compress files with gzip, create SQL scripts, and generate test data from a CREATE TABLE statement. A Data Transformation tool joins, trims and reshapes files, while profiling and comparison tools examine datasets. A masking tool removes personal data before a file is shared, and Data Lineage records each change made to a file.

The site also includes a Cloud Storage Cost Calculator that compares Amazon S3 and Azure Blob Storage costs for a given data size and access pattern, based on the providers' published list prices. Recent files keeps finished results in the browser so they can be reused in another tool, up to 10 files of 100,000 rows each. Three AI tools let users chat with their data through their own Google Gemini API key, and those tools send only a summary of the data, never the full file.

The tools are aimed at people who work with data files and want a quick way to handle them without installing software or creating an account. Files are read and processed on the user's device and are not uploaded to a server, although the site uses analytics to count tool usage.

## About JSON Viewer

JSON Viewer is a browser-based tool that turns JSON, YAML, XML, CSV, TOML and TOON into interactive node-edge diagrams. Graph, collapsible tree and table views show the same data, and values can be edited inside diagram nodes with the raw syntax updating to match.

Users can compare payload versions with a visual diff that marks added, deleted and changed fields, and validate data against JSON Schema drafts 7 and 2020-12 with errors highlighted on the diagram. A Chrome extension and a VS Code extension are also offered, along with native apps for Android and iOS.

Processing runs on the user's device, according to the site, and the free plan covers viewing and exploring with PNG downloads. Paid plans add features such as SVG and PDF export, ad-free use, saved cloud diagrams and an AI assistant. The tool is aimed at developers, engineering leads and data analysts.
