XLSX is Excel's Office Open XML workbook format, replacing the older .xls binary. Reaching a TSV from there is one hop. Converting XLSX to TSV fixes the mismatch between a file you have and the tool that needs to open it. KaijuConverter runs the conversion with the right backend for the job (libreoffice), keeps the source file untouched and deletes both XLSX and TSV copies within two hours. No account required, nothing installed locally. Technical note: XLSX is Excel's Office Open XML workbook format, replacing the older .xls binary. Compare that with TSV is the tab-separated values variant of CSV, common in data pipelines.
Excel Spreadsheet
Source formatXLSX is the modern Microsoft Excel format based on Open XML. It is the industry standard for spreadsheets, supporting formulas, charts, pivot tables, and conditional formatting.
TSV (Tab-Separated Values)
Target formatTSV uses tabs instead of commas to separate values in tabular data. It avoids quoting issues common in CSV when data contains commas, making it popular for scientific and linguistic data.
Why convert XLSX to TSV
TSV is better supported than XLSX in the workflow you are targeting. Converting trades any niche advantages of XLSX for broad compatibility, and the conversion itself is fast because the two formats share the same conceptual content.
HOW TO CONVERT
XLSX → TSV
Upload the XLSX
Drop your file into the browser uploader. We transfer over HTTPS and queue the conversion.
Convert through libreoffice
Our libreoffice-based pipeline reads the XLSX, applies the right decoder and emits a faithful TSV.
Download the TSV
Grab the result when it lands. Both files delete automatically within two hours — nothing lingers on our servers.
Common Use Cases
Cross-platform sharing
Send files to colleagues or clients who expect TSV — no more "what opens this?" emails.
Legacy format rescue
Old archives stuck in XLSX become TSV and survive into modern workflows without special software.
Tool compatibility
Feed existing content into tools that require TSV as input — analytics, editors, CMS platforms and beyond.
Workflow upgrades
Migrate from legacy XLSX pipelines to a TSV-native stack without losing access to source material.
Quality & Compatibility
The conversion preserves the important content and lets you control quality trade-offs through Advanced options. Lossless paths produce TSV output that matches the XLSX content exactly; lossy paths re-encode at transparent defaults unless you request otherwise. Metadata transfers where both formats support it.
Tips for Best Results
- Always keep the original XLSX file alongside the TSV — you may need it later if requirements change.
- Check a small sample of the TSV in its destination application before batch-converting a large archive.
- For recurring conversions, the REST API on paid plans automates the whole pipeline programmatically.
Frequently Asked Questions
Frequently Asked Questions
Yes. The free tier accepts files up to 100 MB without registration, email capture or watermarks. Paid plans raise the size cap, enable batch conversions and provide a REST API for automation, but nothing on the free tier is quality-limited — the output is exactly the same as on any paid plan.
Uploads run over HTTPS, files are processed in isolated containers, and both the source XLSX and the TSV output are auto-deleted within two hours. No account is required, file contents are never logged, and KaijuConverter does not use uploads for AI training. The paid plan adds a signable data-processing agreement for regulated workflows.
Most files finish in well under a minute. Small images and documents are typically ready in a few seconds; large video or audio files scale roughly with duration. Upload speed from your network is usually the dominant factor, not server time.
