Frequently asked questions
Does it handle commas inside quoted fields?
Yes, quoted commas are parsed correctly rather than splitting the field.
Will numbers and booleans convert automatically?
Yes, the tool can guess numbers and true/false values from plain text.
Can I paste CSV text instead of uploading a file?
Yes, pasting text works the same as uploading a file.
Is there a row limit on the CSV I can convert?
No hard limit — large files work the same as small ones.
What happens to my header row?
It's used automatically as the field names in the resulting JSON.
Your files are never uploaded. Gotool.xyz runs entirely as JavaScript in your browser. Your files are processed in memory and never touch a server — nothing to breach, nothing to clean up. Close the tab and it's like it never happened. The only thing we count is which tool ran (just the name, e.g. "merge") so we know what people find useful — never your file, its name, its size, or anything in it.
