Question 1

When do I need to escape?

Accepted Answer

When you want to put text containing double quotes, line breaks or backslashes inside a JSON value — for example to send it to an API or write a config file. Without escaping, the JSON would break.

Question 2

What is unescape for?

Accepted Answer

When you come across a string full of characters like 
 or " (usually JSON that got wrapped more than once), unescape lets you read the real content, for example recovering a whole JSON document stored inside a string.

Question 3

What happens to a string with double quotes at both ends?

Accepted Answer

When unescaping, if the text starts and ends with a double quote, the tool treats it as a complete JSON string and drops those two quotes. If a quote is part of the content, write it as \".

Question 4

Do accented Vietnamese letters get turned into \u codes?

Accepted Answer

No. Accented letters and emoji are kept as they are. When unescaping, codes like \u1ec7 are still read back as normal letters.

Question 5

Why does unescape show an error?

Accepted Answer

Usually a double quote isn't written as ", a backslash is on its own, or there's a real line break in the middle of the string (a line break must be written as 
). Check the reported line and column.

Question 6

Does my data get sent anywhere?

Accepted Answer

No. The content is processed right on your device.

Question 7

Is it free, or do I need an account?

Accepted Answer

It's completely free, no account needed.
