A quick side-by-side before you convert — deeper comparison lives on the full guide.
| Feature | XLSX | TSV |

| Compression | none or container | none |
| Lossy / lossless | Lossless / not lossy | Lossless / not lossy |
| Transparency | Not supported / N/A | Not supported / N/A |
| Best for | Financial models; Operational trackers | Pasting tables from spreadsheets; Data pipelines that prefer tabs |
| Typical size | Small to large depending on data and embedded images | Tiny compared with XLSX for the same rows |
| Browser / web support | Edit via Sheets/Excel online; not a native browser grid format | Download and open in Sheets/Excel; convert in-browser with Format Convertly |
| Compatibility | Opens in Excel, Google Sheets, LibreOffice Calc, and Numbers with occasional formula quirks — the spreadsheet exchange default | Imports cleanly into Excel, Sheets, and scripts that expect tabs; some casual tools still assume CSV by default |

Keep an original copy of your XLSX file if you may need to reconvert later.

TSV format guide →When should I keep XLSX?
Keep XLSX when you still need to edit or when it already matches your audience. XLSX is the business default for spreadsheets: multiple sheets, formulas, pivot-friendly data, and formatting. Use CSV when you only need raw values for import, and PDF when you need a non-editable snapshot of a report.

Frequently Asked Questions
More on quality loss: conversion quality guides · problem-solution guides
Does converting XLSX to TSV reduce quality?
Often no for lossless or remux-style paths. Quality drops when you re-encode with lossy settings, downscale, or flatten features like transparency.
Can you recover quality after converting?
Not from a lossy output alone. Return to the original master (or a better source). Converting to a lossless format does not resurrect discarded detail.
Where can I learn more about conversion quality?
Browse Format Convertly’s Quality guides for topics like whether conversion reduces quality, JPG↔PNG myths, WebP/MP3/MP4 tradeoffs, recovery limits, and generational loss — each links to the right converter.
Are formulas kept?
TSV stores cell values as text — not live Excel formulas.
Is my spreadsheet uploaded?
No. Format Convertly converts locally in the browser.
What is a XLSX file?
XLSX is a Microsoft Excel Open XML workbook for spreadsheets, formulas, and charts. XLSX is the business default for spreadsheets: multiple sheets, formulas, pivot-friendly data, and formatting. Use CSV when you only need raw values for import, and PDF when you need a non-editable snapshot of a report.
What is a TSV file?
TSV is a tab-separated values table — like CSV but with tabs as delimiters. TSV avoids comma collisions inside fields and is common in spreadsheet paste workflows and some bioinformatics/data tools. Convert to CSV when a destination insists on commas.
