Spreadsheets. No account.

Spark Grid 1.3 is out on the Mac App Store. November 6, 2026.

Charts from your files now show on the sheet, and you can move, resize, and edit them. Plus duplicates, tables, tab colors, and a new Settings window.

What’s new in 1.3

• Charts saved in your workbooks appear on the sheet and update as you edit the cells they read. Rest the pointer on a chart to see its values.
• Move and resize any chart, or right-click it to edit, duplicate, bring to front, or delete. Edit Chart changes the type, titles, legend, and each series’ cells and color.
• Insert Chart makes pie and scatter charts, and charts with more than one series.
• The Charts panel lists every chart on the sheet. Click one to go to it.
• Find Duplicates: choose which columns must match, see the repeated rows, then highlight them or remove the extras. Highlights are temporary and clear with Esc.
• Tables: Insert > Table turns a block of cells into a table with a styled header and banded rows. Change its style or remove it from the cell’s menu. Tables in your files show their style.
• The sum, average, and count of the selected cells show at the bottom right. AutoSum adds a total with ⇧⌘T.
• Icon sets can use your own thresholds, as numbers, percents, or percentiles, and run in reverse.
• Sheet tabs show their color, and you can set one from the tab’s menu.

Improved in 1.3

• Settings has tabs for General, Shortcuts, and About. Change any shortcut, search them, and see when one is already in use. Autosave can be turned off or set to save less often.
• Inserting a row or column on a large workbook is much faster.
• Comments are marked with a small speech bubble.
• The arrows that mark hidden rows and columns are easier to see.

Fixed in 1.3

• Workbooks saved with a chart open cleanly in Excel and Numbers.
• Highlighting rules show in Google Sheets after you save.
• Workbooks keep all their highlighting rules when they open.
• Opening a workbook while Spark Grid is already open no longer quits the app.
• Text in workbooks from Excel stays readable in light and dark mode, and keeps its color when you save.
• Charts and color scales update as soon as you type a new value.
• Closing Settings closes only Settings.
• A row keeps its gridlines after AutoSum.
• Icon set checkmarks are the right way up.
• Horizontal bar charts and area charts draw correctly.

1.2

November 4, 2026. Your files come back exactly as you saved them, with dropdown lists, comments, hidden rows and sheets, and much more.

What’s new in 1.2

• Saving keeps everything a workbook had: hidden rows, columns, and sheets, grouped rows, tab colors, protection, page setup, dropdown lists, comments, links, tables, charts, and pivot tables.
• Dropdown lists: pick a value from a cell’s list, or make your own with Data > Dropdown List.
• Comments: rest the pointer on a cell with a red corner to read its comment. Add and edit them from the cell’s menu.
• Hide and unhide rows, columns, and sheets. Small arrows in the headers mark hidden rows and columns; click one to show them again. Hide Sheet and Unhide Sheet are in the Sheet menu.
• Filter by rule: contains, begins with, greater than, between, top and bottom, and dates.
• The fill handle continues numbers, dates, numbered text, and month and day names. Option-drag copies.
• Type a cell or name into the name box to go there. F2 edits the selected cell.
• 37 more functions, including MAXIFS, MINIFS, and the #NUM! error.
• The formula bar shows percents and dates the way the cell does, and typing a date stores a date.

Improved in 1.2

• Files without saved results open and calculate much faster.
• Scrolling draws cells right away instead of filling them in.
• Large format changes, such as alternating row colors on thousands of rows, apply in one step and undo in one step.
• Frozen rows and columns have a clearer edge.
• In dark mode, text on light cell colors stays readable.

Fixed in 1.2

• After a sort, formula columns show the right results for their rows.
• Highlighting rules stay on after you save and reopen a file.
• Totals that add up the same range on two sheets each use their own sheet.
• Data bars keep their scale when you save.
• Typing in a cell and then switching sheets no longer copies the text to the other sheet.
• Undo after switching sheets returns you to where you were.
• Selecting a merged cell highlights all of it.
• ROUND no longer shows -0.
• Open shows only spreadsheet files.

1.1.1

October 29, 2026. Filters you can work in, tabs you can drag, and fixes that keep your files exactly as you left them.

What’s new in 1.1.1

• A filter panel on every column: search its values, see how many rows hold each one, and sort A to Z or Z to A. Click the same sort again to put the rows back.
• The tab bar shows how many rows a filter is showing, with one click to clear it. Filter changes can be undone.
• Drag a sheet tab to move it. The new order saves with the file.
• ⌘-arrow jumps to the edge of your data. Scroll bars appear while you scroll.
• ⌘-click or ⌘-drag removes cells, rows, or columns from a selection.

Fixed in 1.1.1

• Formatting comes back when you reopen a file that has conditional formatting. It was saved in the file all along; opening it dropped it.
• Sorting, filling, and pasting formulas keep their brackets, so (1-F3) stays grouped and the result stays right.
• Undo works after you open a file.
• Copy, cut, and delete skip rows a filter hides, as in Excel.
• Saving after a sort is quick, and quitting no longer waits on a save.
• Memory stays steady when you sort or undo on large sheets.
• ROUND matches Excel on exact half cents. XLOOKUP, XMATCH, IFS, TEXTJOIN, and CONCAT saved by Excel calculate. INDEX across one row works.
• A long chain of formulas on another sheet calculates instead of showing #VALUE!.
• Sheets with color scales stay smooth after you resize rows or columns.
• The grid no longer stretches after you resize the window.
• Drag-select speeds up near the edge and stops where you stop. Filter headers fit their text. Closing a large workbook no longer hangs.

Please check: in 1.1, sorting, filling, or pasting a formula with brackets, such as =A2*(1-B2), could save it without them and change its result. If you did that in a file and saved it, check those formulas and totals.

1.1

October 15, 2026. Big workbooks open faster. The sheet you’re editing stays quick.

What’s new in 1.1

• Large workbooks open much faster and use less memory.
• Saving no longer freezes the window.
• Switching sheets is immediate, and calculated values stay put.
• The sheet you’re editing stays quick. Other sheets update in the background.
• Scrolling back to a page you’ve already seen is instant.
• Heavy formulas, including COUNTIFS, SUMIFS, SUMPRODUCT, and VLOOKUP, calculate faster on large sheets.
• Formula cells show their results. The formula stays in the formula bar.
• Sheet tabs stay in the file’s order.
• Blank formulas stay blank when the file is opened in Excel, instead of showing 0.
• Column widths and row heights stay as you set them after you save and reopen, including a blank row.
• Merged titles draw across the merge at full size, and continue through empty cells when the sentence is wider. Saving still stores the original merge and the original sentence.
• A title in the frozen columns stays put when you scroll. The rest is clipped at the freeze line.
• A section title lower in the sheet stays on its own row and no longer covers the frozen headers.
• Borders no longer cut through a merged title.
• Selecting a merged cell keeps the view on the cell you clicked.
• Command-A in the formula field selects that formula.

Longer notes

• Opening a large workbook is much faster. On the KPI file, the wait dropped from about 15 seconds to about half a second, and the app uses far less memory.
• Saving and autosave no longer freeze the window while the file is written.
• Switching sheets is immediate, and the values already calculated stay put.
• An edit on the sheet you’re looking at stays near-instant. A June edit measured 0.027 seconds. Other sheets update in the background after that.
• Scrolling a page you have already seen is instant. The first visit to a new part of a large sheet can still hitch.
• Heavy formulas on large sheets, including COUNTIFS, SUMIFS, SUMPRODUCT, and VLOOKUP, calculate faster.
• A cell with a formula shows the result. The formula stays in the formula bar.
• Sheet tabs open and save in the same order as Excel.
• Formulas Excel saved as blank stay blank on export, instead of showing 0 before Excel recalculates.
• A column or row you resize is still that size after you save and reopen, including a blank row. Widths and heights already in the file come back the same.
• Merged titles paint across the merge at full size. When the sentence is wider than the merge, it draws through the empty cells to the right. Saving still stores the original merge and the original sentence. Borders and fills no longer cut through the title.
• A title that starts in a frozen column or row stays with that pane. The scrolling part is clipped at the freeze line, so it does not slide under the frozen columns.
• A section title lower in the sheet stays on its own row. It does not paint over the frozen column headers when you scroll.
• Selecting a merged cell keeps the view on the cell you clicked.
• Command-A while the formula field is active selects that field’s text.
