Convert XLS to TSV Online
Limited to 65,536 rows and 256 columns — a fraction of the 1M+ rows in modern XLSX files. Converting to TSV gives you a key advantage: tab characters almost never appear in natural text, eliminating the csv quoting/escaping problems that occur with commas in data. TSV is best for tabular data that contains commas in field values, avoiding the quoting mess of csv.
Why Convert XLS to TSV?
Limited to 65,536 rows and 256 columns — a fraction of the 1M+ rows in modern XLSX files — converting to TSV overcomes this by providing tab characters almost never appear in natural text, eliminating the csv quoting/escaping problems that occur with commas in data
TSV is the right choice when you need to: exchanging genetic and genomic data in bioinformatics pipelines (bed, vcf, gff are tsv-based)
Gain broader compatibility — TSV works with Excel, Google Sheets, Python, R, Unix command-line tools (cut, awk), bioinformatics tools
Your XLS files were created for maintaining backward compatibility with enterprises still using office 2003, but now you need a format suited to different workflows

How to Convert XLS to TSV
Upload your XLS file
Drag your .xls file onto the upload area or click to browse. We accept XLS files up to 100 MB.
Choose TSV as output format
Select .tsv (Tab-Separated Values) from the format list. Configure any format-specific settings to match your requirements.
Convert and download
Click Convert and wait for processing. Your TSV file will be ready to download in seconds. The result is optimized for tabular data that contains commas in field values, avoiding the quoting mess of csv.
Frequently Asked Questions
Is the XLS to TSV conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. Raw tabular data separated by tab characters; cleaner parsing than CSV for data with commas.
How large will my TSV file be compared to the original XLS?
expand_more
XLS files are typically 50 KB – 30 MB, while TSV files are typically 1 KB – 100 MB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted TSV file?
expand_more
TSV is compatible with: Excel, Google Sheets, Python, R, Unix command-line tools (cut, awk), bioinformatics tools.
What is the maximum file size I can convert?
expand_more
PureConverter accepts XLS files up to 100 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between XLS and TSV?
expand_more
XLS (Microsoft Excel Binary Spreadsheet) is best for opening legacy excel 97-2003 spreadsheets from older business systems and archives. TSV (Tab-Separated Values) is best for tabular data that contains commas in field values, avoiding the quoting mess of csv. Key tradeoff: XLS's advantage is binary format that loads faster than xlsx for very large files, with backward compatibility to excel 97, while TSV's advantage is tab characters almost never appear in natural text, eliminating the csv quoting/escaping problems that occur with commas in data.
Pro Tips for XLS to TSV Conversion
Review the output TSV file to ensure all formatting and content transferred correctly from your XLS source
Keep a backup of your original XLS file — while our conversion is reliable, having the source is always recommended
TSV works especially well for: processing linguistic corpora and nlp datasets where text fields contain commas
Did you know? The bioinformatics world standardized on TSV-based formats (BED, SAM, VCF, GFF3) because genomic data is full of commas and semicolons — tab was the only safe delimiter left.
