Convert TSV to Jira Online

Paste a TSV table below, edit it if you need to, and get Jira back. The conversion runs in your browser, so nothing is uploaded, there is no size limit and there is no signup.

The only part of this site that uses a server. The address is sent to it so the page can be fetched, because a browser is not allowed to fetch someone else's page itself. Your own files are never involved.

Nothing here is uploaded. The parsing happens on this page.

What TSV is

TSV is CSV with tabs instead of commas. Because tabs almost never appear inside a value, quoting is rarely needed and the files are easier to read by eye.

Bioinformatics, log processing, and anyone who has copied a block of cells out of a spreadsheet: the clipboard format is TSV.

What Jira is

Jira wiki markup uses double pipes for header cells and single pipes for data cells.

Jira issues, comments and descriptions.

What changes when you convert TSV to Jira

The tab is unambiguous, so there is no delimiter to guess. This is the most reliable of the delimited formats to read.

Empty cells are filled with a single space, because a Jira row with two adjacent pipes collapses the column and shifts everything after it.

What carries over from TSV to Jira

One property of the TSV has no home in Jira, and it is worth knowing which before you convert.

A line break inside a cell ends the row in Jira, so line breaks are replaced rather than carried through.

Jira marks its header cells differently from its data cells, so the first row is written with that marker.

The identifier 007 comes out of the Jira as 007. Reading it as a number would have made it 7, and an id that changes value is worse than one that stays text.

The role "Analyst, data" survives with its comma, in one cell rather than split across two. That is the first thing to check in any converted table, and the usual place a Jira file goes wrong.

The quotes around Jonah "Jo" Pryce are left as a plain quote character in the Jira.

A worked example

Three rows of staff data, with an identifier that has a leading zero, a value containing a comma, a value containing quotes and one blank cell. Those are the four places formats disagree, so they are the four places to look.

Questions

How do I convert TSV to Jira?

Paste your TSV into the box above or drop the file onto it. Check the table in the grid, then copy or download the Jira from the output panel. It takes one step and the data never leaves your browser.

One of my cells has a line break in it - what happens?

A line break would end the row in Jira, so it is replaced instead of carried through. The rest of the cell stays where it belongs.

Is there a limit on file size?

No. The work happens on your own machine, so the limit is your machine's memory rather than an upload cap. A file with tens of thousands of rows converts in a second or two.

Is my data uploaded anywhere?

No. The parsing and generating are done by JavaScript running on this page. You can watch the network tab while you convert and see that nothing is sent.
