AppRanks verdict
Generated from live marketplace data — refreshed daily
Custom Count and Sum is a mixed-rating Google Workspace app with a growing review traction. It is listed in the Creative tools category on Google Workspace Marketplace, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 115 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. The free tier lets you trial the entry feature set without committing a payment method. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical Google Workspace Marketplace listing.

About Custom Count and Sum
How Custom Count and Sum works
Show full descriptionShow less
Stop manually tagging or re-sorting your data just to total up colored cells. Custom Count & Sum adds 23 custom functions to Google Sheets that count, sum, average and filter based on how your cells actually look — background color, font color, and font style (bold, italic, underline, strikethrough).
COLOR & STYLE FUNCTIONS Sum or count cells by background color, font color, or font style — use a reference cell or a hex code. Combine color AND style in a single condition (e.g. only bold red cells).
CROSS-SHEET FUNCTIONS Aggregate the same range across every sheet in your spreadsheet with SUMALLSHEETS, COUNTALLSHEETS and AVERAGEALLSHEETS — no more manually summing tab by tab.
FILTER FUNCTIONS Spill matching values into a clean vertical array with FILTERBGCOLOR, FILTERFONTCOLOR, FILTERFONTSTYLE and FILTERCOLORANDSTYLE — empty cells excluded automatically.
CHECK FUNCTIONS ISFONTSTYLE, ISFONTCOLOR, ISBGCOLOR and ISCOLORANDSTYLE return true/false per cell, matching your range's shape — perfect for conditional logic and audits.
WORKS WITH FUNCTIONS YOU ALREADY KNOW Filter and Check results aren't locked into this add-on — they plug straight into any native Sheets function. Wrap a Filter result in STDEV(), MEDIAN(), or LARGE(); combine a Check result with SUMPRODUCT() or MAXIFS(). No need to wait for a matching built-in function from this add-on — compose it yourself with what Sheets already offers.
Built for anyone who color-codes spreadsheets: project trackers, budget sheets, inventory logs, status boards. If you've ever wished SUM and COUNT understood color, this add-on is for you.
Free forever for smaller ranges. Paid plans unlock larger ranges — monthly, yearly, or a one-time lifetime option. Licenses are per user, not per domain — a domain-wide install doesn't include full access for every domain user on its own. A separate team plan is available for covering a whole domain. Visit base10addons.dev/custom-count-sum for full pricing, FAQ, and domain-license setup details.
