Frequently asked questions
What is worth knowing about turning JSON into CSV
What shape does the input JSON need?
An array of objects sharing the same keys, for instance [{"name":"Mario","age":30},{"name":"Giulia","age":25}]. The keys of the first object become the column headers of the CSV.
How are values containing a comma handled?
Values carrying a comma, a quotation mark or a line break are wrapped in double quotes in the CSV, and any inner quotes are doubled. That is what RFC 4180 lays down, and it is why the file opens cleanly in Excel.
What happens with nested objects?
An object or an array inside a value is turned into a string with JSON.stringify, so it lands in the cell as text. For a spreadsheet it is better to flatten the data first, giving every nested field a column of its own.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
