Hullspark
Small, careful tools that leave your data where it is
Hullspark makes small apps for Confluence and Jira Cloud, for Wix stores, and for Windows. They share two habits.
- Your data stays put — on Atlassian, inside Wix, or on your PC.
- You look before anything changes — a dry run, a read-only scan, or checks before you download.
For Confluence and Jira Cloud
Four apps on the Atlassian Marketplace. Each runs entirely on Atlassian.
-
Label Sweep for Confluence
Confluence has no built-in way to rename, merge or bulk-delete labels. Label Sweep lists every label with its usage count and does all three across pages and blog posts — a dry run shows the affected pages first, and every job leaves a log.
Details, screenshots and FAQ Available on Atlassian Marketplace — free for up to 10 users, 30-day trial for more -
Attachment Sweep for Confluence
Confluence has no built-in way to find attachments that nothing references any more. Attachment Sweep lists them by space, size and date, and moves the ones you pick to the trash after a dry run — never purged, so an admin can restore them.
Details, screenshots and FAQ Available on Atlassian Marketplace — free for up to 10 users, 30-day trial for more -
Page Review Reminders for Confluence
Confluence Cloud keeps review dates in Premium's Content Manager. Page Review Reminders brings a lighter version to every plan: set a reviewer and a due date on a page, and the reviewer is @mentioned in a comment when it comes due. Guide: finding stale pages in Confluence.

Field Sweep for Jira
Which of your Jira custom fields are actually used? Field Sweep checks each one against saved filters, boards and dashboards, and shows what you "Can clean up" and what is "To review". Admin-only. A scan only reads; after a review you can move an unused field to Jira's trash and restore it. It never deletes a field for good. Guide: auditing Jira custom fields.
Details and FAQ Available on Atlassian Marketplace — free for up to 10 users, 30-day trial for more
For Wix stores
Twelve apps on the Wix App Market. Most have a free plan; the app pages list the plans.
-
Japan Shipping Label CSV 送り状CSV（ヤマトB2・クリックポスト）
Still retyping order addresses into a carrier's system? Japan Shipping Label CSV turns your unfulfilled store orders into CSV files in the import layouts of Yamato B2 Cloud and Japan Post Click Post, and warns about bad postal codes and over-long names before you download. Recipient data stays in your browser.

Low Stock Alert 在庫アラート
Want to see which products are running low before they run out? Set one number for every product (or your own number for a product or variant); when stock reaches it, an alert goes to the dashboard bell and the Wix app on your phone, with a morning summary and an order note by supplier. Free with no product limit. It reads products, categories and stock only — no customer or order data. Guide: low stock alerts in Wix Stores

Picking & Packing List ピッキング・梱包リスト
Packing a day of orders one by one means walking to the same shelf again and again. Adds up your open orders into one pick list and prints a packing list per order, as PDF or CSV. Screens in Japanese and English, with sample orders to try. Free up to 20 orders per list, Pro $2.99/month.

Product SEO Bulk Edit 商品 SEO 一括編集
Rewriting product search titles and descriptions one by one is slow, and a bulk edit is hard to take back. Preview current vs. new text side by side, apply only the products you tick, and undo a run from its saved record. Screens in Japanese and English. Free up to 20 products per run, Pro $4.99/month.

Stocktake 棚卸
Updating stock product by product after a shelf count takes a long time. Type the counted quantities, check the gap against your Wix stock, then apply them in one go. Before and after numbers are kept in a history you can export as CSV. Screens in Japanese and English, with sample products to try. Guide: doing a stocktake in Wix Stores.

Sales Journal CSV 売上仕訳CSV
Typing a month of sales into accounting software by hand is slow. Turns paid Wix orders into a CSV in Yayoi import format or freee transaction import format, with rows split by 10% and reduced 8% tax. Customer names and addresses do not go into the CSV. Japanese screen only, for shops in Japan.

Closure Days for Bookings 休業日まとめ設定
Wix Bookings has no “this day is closed” switch. Pick dates or a Japanese-holiday preset; the app first shows how many bookings already exist on those days, then adds a block to every staff member's and room's calendar. Undo removes only the closures the app made, and it never cancels bookings you already have. It covers services with a staff member or a room assigned, and so far it has been tried only on a development site.

Booking List Print & CSV 予約表の印刷と CSV
Printing a day's bookings means exporting a CSV and tidying it first. This app adds one page to your dashboard that lays out each booking's time, service, staff member and head count as a day or week table you can save as an A4 PDF or a CSV. It does not read customer names, phone numbers or email addresses. One day's sheet is free; the by-staff view is Pro. So far it has been tried only on a development site.
Guide: printing the Wix Bookings list On the Wix App Market -
Business Day Calendar 営業日カレンダー
Wix has no holiday mode, so closing days get announced by hand each time. Put a calendar on your site that marks your weekly closing days and Japanese public holidays, and, on the Pro plan, a line for the next shipping day. Screens in Japanese and English, for shops in Japan.
営業日カレンダー: 画面・特徴・よくある質問（日本語） On the Wix App Market — free plan available -
Monthly Booking Calendar 月間予約カレンダー
Wix Bookings shows class times by the week, not by the month. Shows your Wix Bookings classes on your site as a month grid. Tap a date to see that day's classes and the seats left, with a link to book. Classes only, not one-to-one bookings or courses.

Table of Contents by Hullspark ブログ目次
Wix Blog has no built-in table of contents. Builds a table of contents at the top of each blog post from its headings, including Japanese ones. Tap an entry to jump to that heading. Blog posts only.

Allergen Chart for Restaurants アレルゲン一覧表（メニュー用）
A Wix Restaurants menu has no allergen field. For each dish, mark each allergen as contains, does not contain or not entered; a widget shows one card per dish on your site, and visitors can filter out what they must avoid. It does not detect allergens, and you are responsible for what you enter.

For Windows
Two apps on the Microsoft Store. Three more are coming soon and are not on sale yet.
-
Markshot for Windows
Sometimes one image with an arrow and a number says more than three paragraphs. Press Ctrl+Shift+4, drag over the screen, add arrows, boxes, text and step numbers, blur what you can't show, and save as PNG. Free, and nothing is uploaded.
Details, screenshots and FAQ Free on the Microsoft Store

Table Flattener by Hullspark
Reports full of merged cells and two-row headers are hard to sort or load anywhere. Drop in an Excel file: the app estimates the table's layout, shows the original and the result side by side, and saves a new file with one record per row. Your original is not changed. The estimate can be wrong, so check the preview before you save.

-
Document Image Extractor by Hullspark
Copying pictures out of Excel and Word files one by one loses quality. Drop in .xlsx, .docx or .pptx files and the app writes the pictures out as the original data. The free edition does 20 pictures from one file; names with the sheet and cell or slide number are in the full edition.
Details and FAQ 文書の画像まとめ取り出し（日本語） Coming soon to the Microsoft Store -
Path and Filename Checker by Hullspark
A copy that stops without saying which file is hard to chase down by hand. Choose a folder before you move or back it up, and the app lists the paths that are too long and the names that cannot be used. The free edition shows the first 50 rows; entering the destination is in the full edition.
Details and FAQ パス・ファイル名チェッカー（日本語） Coming soon to the Microsoft Store -
Comment & Change List for .docx
Comments from several reviewers end up scattered across copies of the same file. Puts the comments, replies and tracked changes of .docx files in one table, with filters, CSV and copy. Word does not need to be installed.
