HowCurio offline export inspector

Requirements: Python 3. No extra packages.
The script uses the Python standard library and makes no network requests.
Inspect the script before running it. Use only files you are authorized to read.

Confluence HTML package:
  python inspect-export.py confluence "confluence-export" "confluence-report"
Slack public-channel JSON package:
  python inspect-export.py slack "slack-export" "slack-report" "approved"
On Windows with the Python launcher, substitute py -3 for python.

Extract the ZIP to the input folder first. Create no report folder in advance.
Use a new report folder outside the input folder. The script refuses an existing
report folder and never edits input files. A failed run may leave a partial
report folder; fix the source issue and choose a fresh report folder name.

Outputs:
Confluence: links.csv, summary.json.
Slack: messages.csv, file-references.csv, summary.json.
CSV cells beginning with a formula character are prefixed with an apostrophe
for spreadsheet use. Original files and raw message timestamps remain intact.

The synthetic ZIPs are handmade demonstrations, not real product exports.
The sample reports were produced by the included script on those ZIPs.
Confluence demonstration: 2 HTML pages, 8 static references.
Slack demonstration: 6 raw records, 2 declared channels, 2 approved matches,
2 file-reference occurrences and 1 unique nonempty file ID.
The fake example.invalid links are never fetched.

Limits:
Confluence: static href/src inspection only, UTF-8 HTML; no JavaScript, CSS URL,
srcset, remote access, permissions, rights, source-completeness or visual test.
Slack: public channels.json and direct dated channel JSON only; not Enterprise
TXT/private/DM exports. Search checks text and previous text, not block-only
content. Edit/delete events are retained, not replayed into a final transcript.
File reference rows are not downloaded files. Counts include system records.

Real workspace exports and reports contain private content. Keep them in an
authorized location. This script is an inspection aid, not a retention archive,
legal-compliance tool, backup guarantee, or substitute for recipient access.
