How accurate is ImgToSheet.app?
Tested 8–9 October 2026 · updated
Short answer: in ImgToSheet.app's tests on 8–9 October 2026, every cell was read correctly in both test images: a screenshot of a 25-cell budget table, and a sideways phone photo of a printed report with 242 cells, in each of 3 runs. Your own table appears beside your image, so you can confirm any cell at a glance before you download. Try it on your own table.
Results
| Test image | What's in it | Cells | Wrong cells | Time |
|---|---|---|---|---|
| Screenshot | A budget table: 5 columns × 5 rows, with dollar amounts, negative values and percentages | 25 | 0 | about 2 s |
| Phone photo, taken sideways | A printed weighbridge report: 22 rows × 11 columns of dates, times and weights, plus header and total rows | 242 | 0 in 3 of 3 runs | about 23 s |
Why sideways photos needed a fix
Before 8 October 2026, ImgToSheet.app read photos the way they were taken. Read sideways, the 242-cell weighbridge report came back with 18, 67, 28 wrong cells in three runs, mostly values shifted into the row above or below.
ImgToSheet.app now checks which way the text in each image faces, and turns sideways or upside-down photos upright before reading them. With that check, all 3 runs of the same photo had 0 wrong cells, and the header, supplier and total rows were all captured.
The orientation check adds about 4 to 8 seconds to sideways photos. In timing tests it added no measurable time to upright images such as screenshots, which converted in about 2 seconds with or without it.
How the tests were run
- Each image was converted with ImgToSheet.app's production settings: Anthropic's Claude Haiku 5.5 model, with the orientation check on.
- A cell counted as correct only if it matched the image exactly, character for character. Header and total rows were checked as well as the data cells.
- The weighbridge report was converted 3 times, because an AI model's output can vary from one run to the next.
- The expected values were checked against the original image. In the weighbridge report every row's weights also add up (first weight minus second weight equals net weight), and the net weights total the 723.85 printed on the report.
- The weighbridge photo is a third party's document, so it isn't published here.
Getting the best result
- Sharp and straight on. Both test images were sharp and taken straight on, in even light.
- Handwriting. ImgToSheet.app reads handwritten tables too; clear, dark handwriting gives the best result.
- Long tables. Convert a very long table in parts, then paste the rows one after another.
- Any language. ImgToSheet.app keeps text in its original language and script.
Checking your own result
ImgToSheet.app shows your image and the table side by side, so each cell can be compared with the original before export. Every cell is editable, and cells you change are marked, so it's clear which values came from the image and which you corrected.
Questions
How accurate is ImgToSheet.app?
In ImgToSheet.app's own tests on 8–9 October 2026, both test images were read with no wrong cells: a screenshot of a 25-cell budget table, and a sideways phone photo of a printed report with 242 cells, in each of 3 runs. ImgToSheet.app also shows your image beside the table, so any cell can be confirmed at a glance.
Does ImgToSheet.app read sideways photos correctly?
Yes, since 8 October 2026. ImgToSheet.app now turns sideways and upside-down photos upright before reading them. Read sideways, the 242-cell test photo came back with 18 to 67 wrong cells per run; turned upright, it had 0 wrong cells in 3 of 3 runs.
Which AI model does ImgToSheet.app use?
ImgToSheet.app reads tables with Anthropic's Claude Haiku 5.5 model. The same model first checks which way the text in the image faces, so sideways photos can be turned upright.
