Parameters

Send these as form fields next to the file. Names are case-insensitive. If you set one of the documented options below that we don't support yet, the request fails with a 400 that names it instead of returning a file made without it.

ParameterWhat it does
PageOrientationenum, default defaultlandscape also gets the six columns onto one page, with larger text than FitToPage.Values: default, portrait, landscape
FitToPageboolean, default falseFits the table to one page across. The sample uses it: without it the last three columns are drawn on a second PNG.
PageSizeenum, default defaultPaper to draw on; A4 unless you choose.Values: letter, legal, tabloid, ledger, statement, executive, lettersmall, a3, a4, a4small, a5, b4, b5
ScaleintegerFixed zoom in percent instead of fitting.Values: 10–300
ImageResolutioninteger, default 150Pixels per inch: A4 is 992 × 1403 at 120 and 1240 × 1753 at 150. Stored in the PNG when sent.Values: 36–600
PageRangestringOnly these pages.Values: e.g. 1
ImageWidthintegerWidth of each PNG in pixels.Values: 1–20000
ImageHeightintegerHeight of each PNG in pixels.Values: 1–20000
TransparentColorstringExact color to make transparent; the table's gray bands are kept.Values: a color name, #RRGGBB or R,G,B
BackgroundColorstring, default whiteColor behind the page.Values: a color name, #RRGGBB or R,G,B
ColorSpaceenum, default defaultGray or black and white instead of color. rgb gives the same file as the default: three channels, no alpha.Values: rgb, gray, monochrome
FileNamestringStem for the PNG names.
StoreFileboolean, default falseLinks valid for 3 hours.

Not supported yet

Setting one of these to anything but its default returns 400.

Refused when set: AutoFitColumns, ThousandsSeparator, DecimalSeparator, DateFormat.

What carries over, and what doesn't

Kept

  • All six columns on one A4 page, scaled down by FitToPage
  • The gray header band and the shaded every-other row
  • Dates as May 1, 2020 and amounts with their GBP code
  • Lossless pixels, every one opaque, with 120 DPI recorded

Lost or not yet supported

  • Cents on currency cells: 2021.5 is drawn as 2022GBP, 2.99 as 3GBP.
  • Numbers' own fonts, drawn with a substitute sans-serif.
  • Text size: FitToPage shrinks the table, so letters are smaller than at 100% scale.
  • The page header shows the joined sheet and table name, Account_Statement.

Limits

  • One Numbers file per request.
  • Requests up to 10 MB on the Free plan or 100 MB on paid plans, all files and fields together.
  • Up to 2,000 page images per request.
  • A page image can't exceed 16,000 pixels per side or 100,000,000 pixels (413).
  • 120 seconds per conversion, then 504.

Where teams use it

Previews for Numbers uploads

A web app that accepts spreadsheets can show what a .numbers file contains, even though browsers and most servers can't open the format.

Screenshots for support

When a customer sends a Numbers file to support, attach a PNG of it to the ticket so every agent can see the table.

Pictures for reports and slides

Drop a lossless PNG of a small table into a slide or a report where a live spreadsheet isn't needed.

Questions

How do I keep a wide Numbers table on one image?

Send FitToPage=true, as the sample does, or PageOrientation=landscape. With neither, the table is laid out on A4 portrait and its right-hand columns move to a second PNG.

Do I need Numbers or a Mac to convert?

No. The file is opened and drawn on our servers; the sample was saved by Numbers 12 and rendered without any Apple software.

Why do the amounts look rounded?

That is how the currency cells come out when the table is printed: whole units followed by the currency code. The data itself is unchanged; the CSV and XLSX routes return the exact values.
