CamScanner Image to Office#

Overview#

CamScanner provides one-click conversion from images to structured documents, converting image documents to Word or Excel documents while preserving original formatting, greatly improving subsequent editing and processing efficiency. The workflow is a 3-step pipeline: upload the image, convert it, then download the result.

When to Use#

• User wants to convert an image to Word (.docx) or Excel (.xlsx)
• User has an image with tables and needs it as an Excel spreadsheet
• User has an image with text or complex layouts and needs it as an editable Word document

Step 1: Upload Image#

bash

BASE="https://ai-tools.camscanner.com"

IN_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/upload_file/execute" \
  -H "Content-Type: application/octet-stream" \
  --data-binary "@/path/to/image.png" | jq -r '.tool_result.data.file_id')

Response:

json

{
  "code": 200,
  "tool": "upload_file",
  "tool_result": {
    "success": true,
    "data": {
      "file_id": "file_1741857600_ab12cd34ef56",
      "size": 24576
    }
  }
}

Step 2: Convert Image#

bash

OUT_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/convert_image/execute" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$IN_FILE_ID\",\"source_type\":\"image\",\"target_type\":\"TARGET\",\"output_mode\":\"file_id\"}" \
  | jq -r '.tool_result.data.file_id')

Replace TARGET with one of: word, excel.

Response:

json

{
  "code": 200,
  "tool": "convert_image",
  "tool_result": {
    "success": true,
    "data": {
      "file_id": "file_1741857701_9988aabbccdd",
      "target_type": "word"
    }
  }
}

Step 3: Download Result#

bash

curl -sS -X POST "$BASE/v1/tools/download_file/execute?response_mode=raw" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$OUT_FILE_ID\"}" \
  -o /path/to/output.docx

Critical: The response_mode=raw query parameter is required to get the binary file. Without it, the response is JSON.

Quick Reference: Complete Pipeline#

bash

BASE="https://ai-tools.camscanner.com"
INPUT_IMAGE="/path/to/image.png"
TARGET_TYPE="word"          # word | excel
OUTPUT_FILE="/path/to/output.docx"

# Upload
IN_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/upload_file/execute" \
  -H "Content-Type: application/octet-stream" \
  --data-binary "@$INPUT_IMAGE" | jq -r '.tool_result.data.file_id')

# Convert
OUT_FILE_ID=$(curl -sS -X POST "$BASE/v1/tools/convert_image/execute" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$IN_FILE_ID\",\"source_type\":\"image\",\"target_type\":\"$TARGET_TYPE\",\"output_mode\":\"file_id\"}" \
  | jq -r '.tool_result.data.file_id')

# Download
curl -sS -X POST "$BASE/v1/tools/download_file/execute?response_mode=raw" \
  -H "Content-Type: application/json" \
  -d "{\"file_id\":\"$OUT_FILE_ID\"}" \
  -o "$OUTPUT_FILE"

Common Mistakes#

MistakeFixForgetting response_mode=raw on downloadAlways append ?response_mode=raw to the download URLWrong Content-Type on uploadUpload uses application/octet-stream, not multipart/form-dataUsing GET instead of POSTAll three endpoints use POSTMissing source_type in convert requestAlways include "source_type": "image"Missing output_mode in convert requestAlways include "output_mode": "file_id" to get a downloadable file_idWrong output extensionMatch extension to target_type (see table above)

Error Handling#

Check each step before proceeding:

bash

# After upload
if [ -z "$IN_FILE_ID" ] || [ "$IN_FILE_ID" = "null" ]; then
  echo "Upload failed"; exit 1
fi

# After convert
if [ -z "$OUT_FILE_ID" ] || [ "$OUT_FILE_ID" = "null" ]; then
  echo "Conversion failed"; exit 1
fi
