AboutTSV to CSV

Most spreadsheet and BI tools accept CSV as their default import format but choke on raw tab delimiters, so a TSV dump from a database export or a genomic pipeline often needs a quick delimiter swap before it's usable. This tool re-parses the file on tab boundaries and re-emits it as comma-delimited, wrapping any field that already contains a comma in quotes so no data shifts columns. It's a one-way fix aimed at getting command-line and lab-tool output into CSV-only software.

Frequently Asked Questions:

Why would a file be TSV instead of CSV in the first place?

Tab-separated exports are common from database dumps, Linux command-line tools, and bioinformatics or genomic data pipelines.

Does converting the delimiter risk breaking values that contain commas?

No, the converter properly quotes any field containing a comma when it switches to comma delimiters.


Useful for data engineers and bioinformaticians whose tools default to tab delimiters but whose downstream software expects CSV.
