XLS is the legacy binary Excel format from the Office 97-2003 era. That is why users land on this page looking for a TSV copy. A XLS to TSV conversion is one of those tiny jobs that blocks real work until it is done. KaijuConverter turns the XLS into a usable TSV in the background so you can move on — uploads are encrypted in transit and both files disappear automatically within a couple of hours. Worth knowing: XLS is the legacy binary Excel format from the Office 97-2003 era. Meanwhile TSV is the tab-separated values variant of CSV, common in data pipelines.
Excel Spreadsheet (Legacy)
Source formatXLS is the legacy binary format for Microsoft Excel 97-2003 spreadsheets. While superseded by XLSX, it remains common in archived data and older business systems.
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 XLS to TSV
Sending XLS to someone who expects TSV regularly leads to errors or quality loss as the receiving software performs its own silent re-encode. Converting upstream lets you control the quality trade-offs rather than leaving them to an external tool.
HOW TO CONVERT
XLS → TSV
Provide the file
Drag and drop or select a XLS file up to 100 MB. No account required on the free tier.
Run the conversion
We pick the right backend for this pair automatically and produce a TSV that matches the source data exactly.
Retrieve the output
A download link appears as soon as the TSV is ready. For batch jobs, you get a single ZIP download.
Common Use Cases
Mobile device access
Many phones and tablets read TSV natively but not XLS — converting is the fastest fix.
Web publishing
CMSes and web hosts prefer TSV for uploads; XLS may be silently rejected or transcoded.
Automation and scripting
Script-based pipelines typically parse TSV with one-line libraries; XLS support can require custom readers.
Long-term archival
Format-conversion to TSV decouples your archive from a single application and protects against format obsolescence.
Quality & Compatibility
Fidelity depends on how close the two formats sit conceptually. Same-family conversions (document↔document, audio↔audio) keep the essentials intact. Cross-family jobs (image→video, text→PDF) reinterpret the source into a genuinely different artefact, so expect the TSV to emphasise different attributes than the XLS.
Tips for Best Results
- If the XLS contains sensitive data, strip metadata in the TSV export (toggle under Advanced) before sharing publicly.
- Conversion settings that look obscure (bitrate, colour profile, compression level) matter mostly for archival and professional workflows — defaults are fine for everyday use.
- Batch conversions share settings across every file in the job; set them once, apply to many.
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 XLS 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.
