Convert Excel to SQL.

Drop an Excel spreadsheet and get CREATE TABLE + INSERT statements, with column types inferred from the data. It all runs in your browser — no signup, no upload, no watermark.

To convert Excel to SQL, drop or paste an Excel spreadsheet — csvtodashboard parses it into rows and columns in your browser, then emits CREATE TABLE + INSERT statements, with column types inferred from the data. You get CREATE TABLE plus INSERT statements with column types inferred from the data and string values quoted and escaped. Nothing is uploaded; the whole conversion runs on your device.

01 · How it works

Three steps, then done.

This converter reads the first sheet of your .xlsx or .xls workbook (pick another sheet if it has several); the top row becomes the field names and every row below becomes a record, then writes CREATE TABLE + INSERT statements, with column types inferred from the data. Both sides are tabular, so it is a clean, lossless mapping — no nesting to flatten and no structure to guess. Types are inferred as the data is read, and the whole conversion runs locally in your browser, so your file never leaves your device.

i. drop

Drop or paste

Drag a file, click to choose, or paste data directly into the input pane.

ii. detect

We read the shape

Types are inferred so the output is correctly formatted — not strings everywhere.

iii. use it

Copy, download, or dashboard

Copy the output, download it, or hit 'Build dashboard' to chart what's in the data.

02 · Why ours

Smart SQL conversion by default.

Free SQL converters often produce sloppy output — every value quoted, types lost, errors swallowed. Ours infers types where it can, fails loudly when it can't, and pairs the conversion with a one-click path to a dashboard.

  • 01

    Correct types

    Numbers, booleans and nulls are preserved wherever SQL supports them — not every value dumped as a quoted string.

  • 02

    Local-first

    Your file is parsed and converted in your browser — verify in DevTools → Network. Nothing is uploaded, logged, or stored.

  • 03

    Fails loudly

    Malformed input gives a clear, specific error instead of silently wrong output — so you can trust what comes back.

  • 04

    One click to a dashboard

    Every conversion keeps a tabular copy, so you can send the data straight to our visualization tool to chart it.

"Needed a conversion. Ended up with a dashboard. That's the pattern."

Good to know

excel to sql notes.

Format-specific details worth knowing before you convert Excel to SQL.

  • Types are inferred

    Column types (INTEGER, REAL, TEXT) come from the data, not VARCHAR everywhere, so the generated CREATE TABLE matches your actual values.

  • Quotes are escaped

    String values are single-quoted with embedded quotes doubled, as in O''Brien — the standard SQL escape — so the INSERTs run as written.

  • Blanks become NULL

    Empty cells are emitted as NULL rather than an empty string; rename any header that clashes with a SQL reserved word before importing.

03 · FAQ

excel to sql questions.

What Excel input works?
Any .xlsx or .xls workbook. The first sheet is used by default; multi-sheet files show a picker so you choose which one. The top row is treated as the header.
A CREATE TABLE plus INSERT statements. Column types (INTEGER, REAL, TEXT...) are inferred from the values, which are quoted and escaped correctly.
No hard limit. Parsing and conversion run in your browser, with large inputs handled off the main thread so the tab stays responsive — you are bounded only by your device's memory.
No. The entire excel-to-sql conversion happens locally in your browser — the file never touches a server. Watch DevTools → Network to confirm nothing is sent.
