Utilities for handling data

Words Replacer: Ctrl+H on steroids. Make a range of word/phrase replacements on a text sequentially.

Table un-pivot: Convert "wide" or pivoted chart (which is human-friendly) to "narrow" or linear table (which is machine-friendly and workable for visualizations, calculations).

Offline Form : An example of a form in a standalone webpage that saves the submitted data as a local CSV file in your downloads folder. Good for situations where you have to take registrations and have slow or no internet. Works in Google Chrome, Chromium/Iron browser; not in Firefox as of now. Later you can combine the CSV files via commands.
Windows : copy *.csv all.txt
Ubuntu: for f in *.csv; do cat "$f" >> all.txt; echo "">> all.txt; done

Self-referencing CSV to Hierarchical JSON converter : for visualizing tabular data that has nested hierarhcies with rows having parent-child configurations.
