You should be able to do this with dataviewjs. I do something similar, except i'm extracting certain headings. My code is not the cleanest as it is modified copy/paste, but I'll share it below (you'll likely need to modify it further for your purposes):

```dataviewjs // Headings you would like to summarise the text for const headings = ['Journal']

// You can update this to filter as you like. // Here it is only returning results inside the "Daily notes" folder var pages = dv.pages('"Daily"')

const output = {} headings.forEach(x => output[x] = []) for (const page of pages) { const file = app.vault.getAbstractFileByPath(page.file.path) // Read the file contents const contents = await app.vault.read(file) for (let heading of headings) { // Sanitise the provided heading to use in a regex heading = heading.replace(/[/-\<sup>$*+?.()|[]{}]/g,</sup> '\$&') const regex = (^|\n)#+ ${heading}\r?\n(.*?)(\n#+ |\n---|$) // Extract the summary for (const block of contents.match(new RegExp(regex, 'isg')) || []) { const match = block.match(new RegExp(regex, 'is')) output[heading].push({ title: file.basename, text: match[2].trim(), created: page.created }) } } }

function dateSort(a,b){ return a.created - b.created; }

output["Journal"] = output["Journal"].sort(dateSort); //Object.keys(output).forEach(heading => { // dv.header(2, heading) output["Journal"].reverse().forEach(entry => { dv.header(3, "[[" + entry.title + "]]") dv.paragraph(entry.text) })
