Data formats
JSON to CSV
Flatten JSON arrays of objects into spreadsheet-friendly CSV.
APIs return JSON; stakeholders want spreadsheets. Feed an array of objects (or a single object) and get comma-separated output with headers derived from keys. Nested objects are flattened to strings so you can open results in Excel or Google Sheets.

FAQs
How are nested fields handled?›
Nested objects are typically flattened or stringified into a cell—deep structures may need custom export logic.
Can I round-trip back to JSON?›
Use CSV to JSON on this hub; types may become strings—coerce in code if needed.
What about commas inside values?›
Fields are quoted when necessary so commas inside cells do not break the format.
General
Do these tools send my data to Exemplar’s servers?›
By default, conversion and formatting run entirely in your browser. Nothing is uploaded to Exemplar for normal paste-and-transform workflows. Tools that deliberately open an external service (for example, a third-party speed test) are called out on the page.
Do I need an account or install anything?›
No account is required. Everything runs in the browser—there is nothing to install for these utilities. They complement the Exemplar platform but work standalone.
Are these utilities open-source or the same as other sites?›
These pages are built for Exemplar’s audience (developers working with APIs, config, and ops data). Behavior may differ slightly from other online tools; always verify critical output in your own environment.
Are there size or performance limits?›
Very large inputs can slow down or crash the tab—especially for images, huge JSON, or multi‑MB HAR files. For production-scale data, prefer local CLI tools, streaming parsers, or your own pipelines.
Can I use output in production?›
Yes, when you have validated it. Parsers and formatters here aim to be helpful for everyday tasks but are not a substitute for tests, schema validation, or security review where it matters.
Where can I read more about privacy?›
