Query local JSON with JSONPath
Filter nested JSON with a fixed RFC 9535 profile and export complete matched values with original locations.
BED overlap count matrix
Count each sample interval that overlaps each reference span, including duplicate and nested records. Keep every reference field, the chosen sample order, exact originals and a complete source report.
CSV ↔ vCard contact migration
Map contact columns locally, preserve repeated fields and structured values, and export editable CSV or UTF-8 vCard 3.0 with a complete sidecar.
BibTeX and RIS citation migration
Convert local article, book and conference-paper references with ordered authors, complete source records and a field mapping report.
Count rainflow cycles with original source indices
Count every cycle from a complete local CSV, preserve original sample/time positions and export the full range–mean matrix.
Psychrometric series chart
Turn a complete temperature/RH series into rowwise moist-air properties and an all-point chart, preserving original and invalid rows.
Column correlation matrix
Compute Pearson or Spearman correlations from a complete CSV, preserving original labels, repeated selections, each pair’s effective N and status.
Contingency table inference
Calculate a chi-square independence test directly from aggregate counts, with complete expected cells, contributions and residuals.
Fractional factorial plan
Turn factor names, signed generators and physical levels into a complete execution plan, every defining relation and every alias term.
Control model frequency response
Complete SISO continuous-model response with certified roots and explicit phase branches.
Classification Rank Budget
Rank complete labeled scores and inspect every top-K review budget with exact prefix counts.
Thermal comfort series
Calculate a complete PMV/PPD measurement series with explicit row states and six reproducible downloads.
