Convert CSV to TSV for Spreadsheets and Database Imports
When this applies
Reach for this flow when European decimals or address fields break naive comma parsers. Tabs often reduce quoting noise in console tools and some warehouse loaders—still validate because embedded tabs in free-text columns poison TSV just as badly.
Tool to use
Convert CSV to tab-separated values.
Open CSV to TSV →Steps
- 1Profile odd commas inside quoted fields before converting blindly.
- 2Convert and open in a plain text viewer to confirm tabs—not spaces—separate columns.
- 3Re-import into a scratch table with aggressive type detection disabled when testing.
- 4Document delimiter expectations beside the file for teammates via README snippets.
Examples
- Redshift COPY prefers TSV when comma-heavy descriptions flood CSV quotes.
- Bioinformatics handoffs exchange tabbed matrices without CSV escaping roulette.
What to avoid
- Allowing literal tab characters inside comment fields without escaping.
- Assuming Excel saved UTF-8 when the importer expects Latin-1.
- Skipping row counts versus source after conversion.

FAQ
Escape tabs in cells?
Sanitize or reject rows with stray tabs; converters cannot guess intent.
Excel friendly?
Import via data wizard specifying tab delimiters; double-click defaults may mangle types.
