How to use this office tool

  1. Choose a spreadsheet, worksheet, and header row.
  2. Build the percentile table for all detected numeric columns.
  3. Review sample counts and download the XLSX summary.

What this tool does

The analyzer finds numeric columns in the selected worksheet and generates a new XLSX summary using an inclusive, linearly interpolated percentile method.

Numeric column values → sorted samples → interpolated percentile table

Blank cells, nonnumeric text, and formulas without stored numeric results are excluded from percentile calculations.

Supported formats

Files are processed locally. XLSX and XLS workbooks are read with SheetJS; CSV and TSV files are parsed with delimiter-aware handling. Advanced Excel features may not be preserved in generated files.

FAQ

Which percentile method is used?

The table uses an inclusive linear interpolation method over sorted numeric values.

Are blank and text cells included?

No. Only finite numeric values and stored numeric formula results contribute to the calculations.

Can I calculate percentiles for several columns?

Yes. Every column with at least one numeric value receives its own summary row.

Why might Excel show a slightly different percentile?

Different applications may use inclusive, exclusive, or nearest-rank definitions, especially with small samples.

Which statistics are included?

The output includes count, minimum, 5th, 10th, 25th, 50th, 75th, 90th, 95th percentiles, and maximum.
