fill-template

From the author

Use when the user wants to "fill in this letter for each person", "mail merge", "generate letters for this list", "turn this filled letter into a template", or hands over a template plus a list. Bulk-fills ONE master template — a Word (.docx) letter/form or an Excel (.xlsx) form — from a data table, one filled file per row (mail-merge); or the reverse: extract a reusable tokenised .docx template + data-table skeleton from a filled example document, confirm the mapping, then fill. Reads the master, proposes a TOKENISED version (varying parts become {{tokens}}), confirms the mapping, then regenerates one output per data row, preserving the master's layout exactly. Data is an .xlsx or .csv (one row per output); outputs are one named file per record. Never invents: a token with no data is a VISIBLE flag, never a silent blank. Runs fully local and generates files only — it does not send, post or sign. Extract is .docx only this round (not .xlsx). Not a substitute for a hand-crafted single letter.
