Frequently asked questions
Is converting TSV to JSON Lines free?
Yes. There is no sign-up, no watermark and no limit on the number of files.
Are my files uploaded?
No. Everything runs in your browser, so your files are never uploaded to a server. That also makes it fast, because nothing has to travel over the network.
Will I lose quality converting TSV to JSON Lines?
No noticeable loss: the conversion keeps the content of your TSV file intact.
Can I convert several files at once?
Yes. Drop as many TSV files as you like. They are converted one after another and you can download them individually or as a ZIP.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device's memory, since the conversion runs locally.
What is TSV?
TSV is like CSV but separates columns with tabs, which avoids trouble with commas in values.
What is JSON Lines?
JSON Lines stores one JSON record per line, which is handy for logs, streaming and large datasets.
