Tips for Converting XLS to TSV
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
Microsoft Excel 97-2003 Spreadsheet has a known limitation: proprietary binary format that is harder to parse than XLSX. TSV File addresses this with a key advantage: less ambiguous than CSV since tabs rarely appear in data values. Converting from XLS to TSV is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
Microsoft Excel 97-2003 Spreadsheet is most commonly used for legacy spreadsheet archives from pre-2007 systems, while TSV File is the standard for bioinformatics data interchange and genomic datasets. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where XLS is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the TSV output
TSV File has its own limitation worth understanding before you commit: less universally recognized than CSV by business applications. After the conversion completes, open the TSV file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Understand the editing vs. viewing trade-off
Some document formats are designed for editing (DOCX, ODT), while others are intended for final distribution (PDF). Converting to PDF locks in your formatting and makes it difficult to edit the content later. If you plan to revise the document further, keep an editable source copy before converting.

Source Format
Microsoft Excel 97-2003 Spreadsheet
application/vnd.ms-excelXLS is the legacy binary spreadsheet format used by Microsoft Excel from version 97 through 2003. It stores worksheets with data, formulas, charts, and formatting in a proprietary binary structure. While superseded by XLSX, XLS files remain prevalent in legacy business systems and archives.
Advantages
- Compatible with all versions of Microsoft Excel
- Smaller file sizes for simple spreadsheets in some cases
- Extensive legacy data in business and government systems
Limitations
- Proprietary binary format that is harder to parse than XLSX
- Row limit of 65,536 and column limit of 256
- Vulnerable to macro-based malware and security exploits
Common Uses
- Legacy spreadsheet archives from pre-2007 systems
- Compatibility with older Excel-based business applications
- Data exchange with systems that only support XLS format
Target Format
TSV File
text/tab-separated-valuesTSV (Tab-Separated Values) is a plain-text tabular data format identical in concept to CSV but using tab characters instead of commas as delimiters. Tabs are less likely to appear naturally in data fields compared to commas, reducing the need for quoting and escaping. TSV is commonly used in bioinformatics, data science, and text processing.
Advantages
- Less ambiguous than CSV since tabs rarely appear in data values
- Simple parsing with no need for complex quoting rules in most cases
- Human-readable and easily processed by command-line tools
Limitations
- Less universally recognized than CSV by business applications
- Tab characters can be invisible and confusing in text editors
- No standard for data types, formatting, or metadata
Common Uses
- Bioinformatics data interchange and genomic datasets
- Unix command-line data processing and text manipulation
- Data exchange between scientific and research applications
